What mixture to choose for masonry oven. Proper preparation of mortar for bricklaying

Before buying a masonry mixture, determine why you need it and in what conditions the product will be. As a rule, the main elements of the composition of such a mixture are traditional cement and sand. But now more often we can find mixtures with drying rate controllers and antifreeze materials. For example, there are mixtures that have increased resistance to moisture or that add ductility. A good solution will ideally lie on the prepared surface, quickly set and provide the building with durability.

What else you need to know when choosing masonry mix? This is what everyone building material, whether tile or brick, has its own adhesive ability, and in a simple way - the degree of stickiness. Its percentage must be considered when choosing a dry mixture. There are special mixtures for silicate, ceramic bricks, choosing which, you will get a good result.

You can realize your design idea by choosing the color of the mixture to match the shade of your brick.Masonry mix can match the piece material in tone, and contrast with it - this is your personal choice of the master.

If you need increased heat storage in the room, then your choice should fall on special heat-insulating mixtures, which are combined with hollow, expanded clay concrete blocks, as well as cellular concrete blocks.

Gas-silicate and aerated concrete material is used in tandem with adhesive thin-layer mixtures, which are placed to a height of not more than 3 millimeters.

Modern high-quality mixes will help you fill any seams and hermetically “pack” all building elements. You can be sure that with proper use you will get the perfect result!

Masonry mixes for a brick

How to prepare a solution for masonry? Very simple: add the indicated amount of water to it and stir, wait 15 minutes tomasonry mix   well dissolved. But be careful: the resulting cement is only suitable for a few hours. If it happens that you have added too much water to the solution, then add some more dry mixture to compensate for the amount of water.

Remember that using too thin a solution is dangerous - this will adversely affect the quality of the entire building. Then prepare the surface before working with it: remove grease, paint or dust for better adhesion of the elements using a masonry mixture. During operation and for a couple of days after, try to avoid temperature differences (optimally - from ten to twenty-five degrees Celsius), so that the mixture grasps well and you have no problems with further actions: plastering or painting.

The service life of a building depends not only on the selected material for construction, but also on the installation composition selected for the adhesion of brickwork, blocks. The masonry mixture for bricks must be strong, durable in order to maintain the solidity of the wall panel. It is important to know that masonry mixtures are available for both ordinary construction and clinker, chamotte, facing brick. Manufacturing technology is quite simple, but requires strict observance of the rules. Otherwise, poorly prepared substance will lead to the destruction of the entire structure.

Types of mixtures and their purpose

There are several types of mortars for laying bricks:

• Cement, characterized by high strength, rigidity;
• Cement-clay, where pure clay introduced into the solution provides high water-repellent qualities;
• Cement-lime, prepared with the addition of lime milk. They are characterized by high ductility, good adhesion.
• Calcium mixtures are not the best, as they have reduced strength, are brittle and therefore indicated for use in low-rise construction.

The masonry composition is obtained by mixing dry fillers with water. If this is a factory mixture, compliance with the instructions is mandatory. Reducing the flow rate of the mixture depends on the speed of laying out the material, so it is much better to prepare small portions of the composition in order to produce them before drying.

Universal mixture

Shown for construction work  with brick, made on the basis of cement, sand and water. Sometimes plasticizers are included in the composition, for example, special anti-frost additives that allow you to work with the composition even during periods of severe temperature drops. The concept of universality applies to many varieties of compositions, for example, dry masonry is also included in this registry.

Universal composition suitable for laying ordinary brick. A cement-based mortar is used in this case. The proportions depend on the brand of cement: 1: 4, if it is the M400 brand, 1: 5 in the case of choosing the M500 brand. The composition is supplemented with dry clean sand and water. As a filler, you can use lime, which gives viscosity, as a result of which the solution better fills the voids. However, the composition with milk of lime is contraindicated in places of high humidity.

There is a ready-made universal mixture M150, in which plasticizers and water-repellent compounds can already be added. The price of the composition is from $ 12 per bag of 12-15 kg. The availability and quality of the solution allow it to be used quite widely. And the possibility of laying out not only ordinary construction, but also clinker, silicate brick  adds virtues.

White masonry mix

This is a composition that is used either for masonry cladding, or to restore the joints of buildings that have been in operation for more than one year. The composition of the mixture includes high-quality cement, plasticizers, milk of lime, sand and water. In addition to excellent aesthetic characteristics, the solution is notable for its strength, elasticity and practicality. Water absorption is kept within 3-10%, consumption per 1 m2 is not more than 1.6 kg.

The price of the mixture varies between $ 2-2.5 per bag from 10 kg. But due to the small expense, the need for application for facing work, the composition is popular.

Important! The white masonry mixture has a water-holding ability (98%), which is extremely necessary for facing bricks - the finish lasts much longer and does not lose its quality indicators.

Clinker Brick Mix

Due to some specific characteristics of the material, the masonry mix for clinker bricks is different from universal. Mineral binders are required in the composition, which minimizes the risk of shrinkage cracks.

Advice! Choosing a mortar for bricks with a reduced property of water absorption, you should choose a solution with a Rhine track - the ingredient ensures the preservation of the color filling of the product.

The price of such a mixture is higher than the usual (from $ 30), but it is better to buy it. If the construction is done with high-quality clinker bricks, then buying a cheap mortar can reduce all finishing work to zero.

Color compounds

Colored masonry mixtures for bricks include a coloring pigment, polymers. It is thanks to the polymer fillers that the seams do not change the color scheme when exposed to the external environment. A lot of colored compositions for clinker bricks. Pure fine-grained sand as a filler and polymers guarantee reduced water absorption and high plasticity of the solution. A wide color spectrum allows the execution of any design decisions.

Advice! If you use colored compounds only for joint stitching, the consumption will be significantly reduced, which is important at prices for the composition from $ 50.

Mixtures for aggressive environments

These are the compounds used for work in areas of high temperature and humidity indicators. As a rule, these are rooms of mines, production shops and other special purposes. The composition of the solution always includes refractory powders, clay, sand. High plasticity, practicality of the composition is achieved by proper preparation technology: water is poured into the dry ingredients and mixed until the clay dissolves. Then the solution is infused for 3 hours, then water is added again. The correct consistency - the mass is dense, stable, but plastic. Easier - a lump from a shovel slides slowly, but surely. Such a substance is suitable for laying fireclay bricks used in the construction of stoves, fireplaces, chimneys. The price of the mortar is from $ 35, but it can withstand temperatures up to +1600 C, which is especially important if refractory bricks are used for calculation.

Important! All formulations and standards for mixtures are specified in GOST 28913-98.

How to make a mixture

If you need to quickly and easily prepare a mortar for masonry, ready-made dry mixes are sold in stores, which you only need to dilute with water. But if there is time, sand, cement, water, then the mixture is prepared independently:

1. The sand is sifted;
2. Cement is mixed with sand depending on the brand of cement;
3. Water is added, a solution of the desired consistency is mixed.

Knead the composition for at least 5-6 minutes so that all components mix well. Pour into the dry ingredients a third of the water first, then add the rest. The standard water flow rate is 0.6 parts, but it all depends on the desired viscosity of the solution.

Important! The cleaner the sand, the stronger and better the solution. Clay is introduced only in dry powder form. Milk of lime is added instead of part of the water. Plasticizers are sold in specialized stores and must be added strictly according to the instructions.

For refractory bricks, the solution is made of 60% clay, 30% sand, 10% cement. It turns out to be cheaper than the factory one, but there is no refractory component, therefore, the installation of fireclay bricks should be accompanied by refractory plaster, where 20-25% is liquid glass.

The flow rate of the solution depends on the thickness and size of the blocks. But you can calculate in advance how much mixture will be needed per square meter:

1. Calculate the volume of masonry with the exception of doors, windows;
2. Based on the data that 0.3 m3 of mixture is needed per 1 m3, the total volume of the solution is calculated;
3. The resulting proportions will allow you to calculate the right amount  cement.

The volume of masonry is calculated simply: 1 brick has standard sizes, it is not difficult to calculate the number of pieces per 1m3, and then calculate the total area of \u200b\u200bthe desired brick masonry. And remember that the faster the solution is used, the lower its consumption.

Using masonry  in construction involves the mandatory preparation of a solution. Its composition and consistency depend on many factors: what stage of work it is intended for, the type of brick used, climatic conditions and more. Having studied the features of preparing the mixture for bricklaying, you will protect the walls of the future design from many unpleasant moments.

Types of solutions, their characteristics

The key task of the masonry mortar is to perform the connecting function between the elements of the erected brick structure. The consumption of the mixture is usually determined per cubic meter of brickwork. An important condition is the quality of the building material used, in the presence of a large number of fuzzy faces of the masonry mixture, more than planned is required. The basic principles for choosing a solution are as follows:

• in summer and winter, the compositions have differences;
• surface and ground structures require an individual approach in the preparation of the mixture;
• construction using clinker brick involves a special composition of masonry mortar;
• facial masonry necessitates measures to prevent the formation of salt stains;
• the construction of the furnace structure eliminates the use of cement mortar.

The binder included in the solution determines whether it will be hydraulic or air hardened. The presence of one binder component indicates a simple mixture, this includes lime and cement compositions. Several binders form a complex mixture for masonry, characterized by additional properties. So the introduced clay successfully performs the function of a plasticizer, giving the mortar for masonry plasticity. Seams made from such a complex composition successfully resist cracking during expansion.

Depending on the initial parameters, in construction I use the following types of solutions:

• The most commonly used cement mixture. It is characterized by high strength and rigidity. Suitable for private construction and for the construction of multi-storey structures.
• Cement-clay mixes are one step lower in strength. The preparation of the composition is preceded by a thorough cleaning of clay from impurities and its grinding.
• The cement-lime mixture is inferior in strength to the previous composition. During its preparation, the lime dough is diluted with water to a liquid state and purified by filtering through a construction sieve. The resulting liquid is gradually added to the dry cement-sand mixture. Lime here plays the role of a plasticizer; ceramic or silicate bricks are combined with the resulting composition.
• The use of lime solutions is limited. They are significantly inferior in strength to the cement composition, therefore, they are used exclusively for low structures. Among the advantages, low thermal conductivity is noted.

How to make a quality mix

Any workflow requires tools and equipment. For kneading you will need:

• a container in the form of a trough or duct with high walls;
• shovel;
• a sieve having cells of 3x3 mm or more;
• at least 3 buckets;
• trowel and embroidery;
• with large volumes, a concrete mixer will not be superfluous.

The connection of silicate or ceramic bricks is carried out using a cement-sand mixture. Mountain, river or artificial sand is suitable for the role of a filler, the latter has a reduced weight.

Important ! The sand is pre-cleaned by sieving.

Initially, sand and cement are mixed in a dry state, then water is poured in small doses until the desired degree of viscosity is formed. With significant volumes, specialists regularly engaged in bricklaying advise to pour the components of the future mixture into layers in the form of beds, the total height should not exceed 30 cm. The resulting ridge is mixed several times with shovels and passed through a sieve.

Upon reaching the optimal consistency of the mixture, a homogeneous composition is elastic. If the masonry is carried out alone or together, it is impractical to induce large volumes, since the flow rate moves slowly and the solution solidifies quickly. For individual work, there is enough volume, which will be used up during the next three hours. When laying one and a half bricks, consider the lower consumption of connecting material.

Proportion Options

Most often, the mixture for bricklaying has the following proportions:

• cement - 1 part;
• sand - 3 parts;
• water - 0.5 parts.

These indicators vary depending on the requirements for the composition and brand of cement. For example, masonry clinker brick requires a composition of high viscosity, since the facing brick has low water absorption. Before starting work, it is better to study the reference tables of SNiPs, which take into account the following factors:

• soil condition;
• climatic conditions;
• masonry place (underground or ground, external walls or internal partitions, etc.)

Improve the properties of the mixture for masonry allows dispersion additives in the form of lime and clay. To increase the strength of the composition, lime solutions are supplemented with hammer slags or active siliceous additives. The following table contains approximate relationships between the elements of the mixture for masonry:

Note! The period of solidification of the mixture depends on weather conditions: dampness prevents the rapid solidification of the mixture for bricklaying, it retains astringent properties longer; heat accelerates solidification.

To increase the viscosity of the prepared mixture when laying bricks in a hot climate will allow the addition of water in a small amount and regular mixing.

Solution requirements

High-quality brick laying involves the use of an elastic mortar when the correct ratio of density to liquid is selected. Especially this should be adhered to when laying facing bricks for laying. If the mixture "breaks", this indicates an excess of sand in it. The characteristic properties of an elastic mixture are ease of application and distribution over the surface of a brick. The correct mortar ensures full filling of the space between the bricks, which further contributes to the formation of a high-quality seam. In the process of bricklaying, the excess mixture appears on all sides. The peculiarity of the elastic composition is that it will not leak, the wall remains clean. In the end, the process of bricklaying will complete faster, due to the absence of distracting procedures for fixing seams and cleaning walls.

The strength of the mortar is determined by the brand of cement used. The number after the letter M indicates how much weight 1 cm 2 of the mixture can withstand. Portland cement labeled 400-500 provides maximum reliability and prevents the risk of efflorescence. To obtain a high-quality mixture with the desired elasticity, measure the components of the future solution with specific doses, for this purpose, containers with a fixed volume or classic scales are used.

Among professional builders, there is a division of the mixture for bricklaying in the following categories:

• Skinny. Excessive aggregate (sand) provokes frequent tears. They do not correspond to the optimal strength of the brickwork.
• Normal mixtures are characterized by a proportional composition of the binder component and aggregate.
• Fatty compositions are characterized by an excessive presence of a cementing element, which subsequently leads to cracking of the mortar during brick laying.

To determine the fat content in lime and clay solutions, an ordinary shovel is used:

• in the absence of adhesion - the composition is lean and requires the addition of binders;
• individual adhering clots indicate a quality mixture with the correct elasticity;
• a sticky shovel, which is difficult to clean, indicates a greasy solution that must be diluted with a filler.

Factors determining the consumption of masonry mortar

The following factors influence the consumption of a mixture for bricklaying:

• The thickness of the seam between the bricks. Given their length, exceeding the norm by even a few millimeters will lead to a significant increase in the volume of solution used.
• Wall thickness.
• Type of bricks applied. Here, the flow rate increases when laying facing bricks, so take care of increasing the total volume of the mortar by 20-30%.

To find out the flow rate of the mixture, averaged data are used, according to which 25-30% of the volume of mortar falls on 1 m 3 of brickwork. Based on this, to determine the consumption of masonry composition, it is necessary to know the volume of brickwork. The algorithm of actions that allows calculating the need for cement includes the following steps:

• The total volume of brickwork is calculated. Remember to subtract the area of \u200b\u200bthe door and window openings.
• Based on the information that in 1 m 3 of masonry the proportion of mortar is 0.25-, 30 m 3, calculate the total volume of the building mixture.
• Based on the required proportion, determine the need for cement.

Important ! Calculations with volumetric dosages necessarily take into account the density of cement.

Correctly made calculations will allow you not to get out of the planned schedule of work and complete the entire process in a timely manner.

Masonry is the foundation of many buildings. With the help of bricks, structures for various purposes and strength are being erected. Proper preparation of mortar for bricklaying largely determines the quality and reliability of the entire construction.

In order to build a high-quality and reliable brick structure, it is necessary to properly prepare the solution.

By changing the composition of solutions, one can influence the parameters brick walls. Various additives can change the possibilities of such a binder. The preparation of the mixture for bricklaying is a fairly simple, but very responsible matter. Compliance with manufacturing technology and composition is the key to the strength of the house.

Features of mortar for bricklaying

In general, a brick masonry mortar is an aqueous mixture of a binder with a filler, into which additives can be added to impart additional properties. It should be remembered that the mortar for masonry is noticeably different from mixtures intended for other purposes (for example, plaster).

As a binder (base), cement and lime are used, each individually or in combination. The main filler is sand. Clay can be used in combination with it. In addition, plasticizers and other additives can be introduced into the mixture to increase heat resistance, resistance to moisture, steam, etc. The use of detergents to increase elasticity is common enough.

A number of requirements are imposed on mortars for masonry brick walls. They must have good adhesion to the brick, which ensures reliable adhesion to it. It should be flexible enough to evenly effortlessly spread over the surface and fill in the bumps in the brick. It is important that the mixture after hardening has a high compressive strength. The pour time of the solution should allow it to be used. In addition, additional conditions include thermal resistance, resistance to moisture.

Analysis of the use of various binders shows the following. Lime mortar has high elasticity and good thermal insulation properties, but has low mechanical strength. It can be used only in minor buildings - a fence, light outbuildings. Cement mortar  It has increased mechanical strength, excellent adhesion to bricks, but is considered a cold and not sufficiently ductile material. Many disadvantages are eliminated by using a cement-lime mortar, which is quite durable and flexible. It is widely used in the preparation of mortars for bricklaying.

Basic properties

Solutions have their own brands, which can be assigned even to those options that are prepared with your own hands. It is customary to fix the brand in the following form: for example, M50 is a solution having a compressive strength of 50 kg / cm³. The greatest applications for bricklaying are options M10, M25, M50 and M75. M100 and higher solutions are used in particularly robust structures. Strength test can be carried out independently - a cube of a solution with a side of 7 cm after 28 days of drying is subjected to compression stress.

An important standardized parameter is mobility. To determine the mobility, a cone with an angle of 30º at a height of 15 cm, having a mass of 300 g, is immersed in a fresh solution. It is customary to consider mobility by the depth of immersion of the cone (in cm) for 1 hour. For masonry of red brick, mobility should be no more than 13, and for hollow bricks - no more than 8. When building in warm weather, mixtures with high mobility are recommended.

Mix Component Requirements

When a solution is prepared, particular attention is paid to the quality of the components. Water for the solution should not contain impurities, oils, dirt. Well and spring water show the best results. If the mixture is prepared in the summer, then the water should be cold, i.e. not warmed by direct sunlight; and in winter, on the contrary, it needs to be heated a little. The sand is used well cleaned and sifted. It should not contain clay and impurities. Cement defines the basic properties, so it should be checked carefully. When buying, you should watch that the packaging is not broken. Cement stored in a humid atmosphere is unsuitable. Lime should be used in slaked form. Detergents can be used practically any - shampoo, laundry detergent, etc. Do not use cleaners only.

Do-it-yourself simple cooking

The simplest mortar for bricklaying is an aqueous mixture of two components (cement or lime with sand). In the construction of houses is a simple cement-sand mortar. It is prepared in proportion: for one part of cement 3 parts of sand. Such a mixture in dry form is loaded into a pan-type container (with an increased area) and thoroughly mixed. When the mixture becomes a uniform gray color, little by little water is added to it with constant stirring. The mixture should acquire a viscous consistency, allowing its application to the surface; Do not be too thin. The last condition is easy to verify by tilting the container by 40º - nothing should pour out.

If the question arose, how to prepare a mortar for bricklaying of different strengths, i.e. different brands, you should change the ratio of components. Practically, it was determined that the M50 solution is obtained by diluting a mixture of cement (Portland 300 brand) and sand in a ratio of 1: 5; M75 - with a ratio of 1: 3; M100 - 1: 2; M150 - 1: 1.5.

Cement-sand mortar with lime

When it is necessary to solve the question of how to prepare a solution with increased elasticity, it is worth adding slaked lime. Such a solution will retain its plasticity for up to 5 hours. It is undesirable to use this solution in the basement of the outer wall with increased soil moisture. A mixture is recommended in the following ratio of cement, lime and sand: 1: 1: 4 (calculated on the use of Portland 400 cement), which corresponds to the M75 grade. For the M50 brand, this proportion will be 1: 0.5: 4.5.

The preparation of the solution is as follows. First, a lime dough is prepared - a mixture of lime and sand is diluted in water with stirring until the consistency of thick sour cream. Then the cement is mixed with lime dough with the addition of water with constant stirring.

During construction brick house  as a bonding material, a special masonry mixture for bricks is used. The best option is a solution whose consistency meets the requirements.

A solution of medium density is well suited for masonry, capable of laying well on the product and at the same time being held on its surface until it hardens. In addition, it is important that the solution has good adhesion, is durable and does not absorb excess moisture.

To build a reliable structure that meets the requirements of strength and durability, a high-quality mixture should be used, in the preparation of which the technology and the recommendations of specialists were followed. The creation of such a solution requires knowledge of the varieties of existing mixtures.

Features of solutions

The choice of the type of masonry mixture should be based on the requirements for the construction of a particular facility.

For example, the construction of the bath involves the use of a plastic solution that can fill all the seams, voids and surface irregularities. The requirements for the composition include various characteristics. The solution should have sufficient strength, which will not cause deformation of the future wall. The density and rate of hardening of the mixture should correspond to the speed of the work performed. The time period required for complete hardening of the composition depends on the components used and its purpose.

The classic simple composition assumes the presence of water, sand and cement. This composition is used in the construction of small houses or auxiliary buildings. For its manufacture, cement 400-500, pure water and sand fractions up to 2 mm are used.

The amount of sand used in the composition determines how durable the finished solution will be. The smaller it is, the more reliable will be the solution itself. And, accordingly, vice versa. The proportions that are used most often:

• 5 parts of sand and 1 part of cement (M25);
• 4 parts of sand and 1 part of cement (M50);
• 3 parts of sand and 1 part of cement (M75).

The construction of particularly strong walls is carried out using a mixture of M50 and M75, where the use of an additional ingredient - sand, is reduced. Fields of application of such a mixture are columnar foundations, work in conditions of high humidity and the construction of clinker brick houses.

For other construction needs, a M25 grade solution may be applicable. The preparation of such a mixture per 1 cubic meter of masonry requires:

• water (250 liters);
• cement (268 kg);
• sand (1064 kg);
• concrete mixer;
• bucket and hose.

Solution preparation

In order to prepare a masonry mortar for a brick, it is recommended to use river sand. Previously, it should be sieved and separated from all kinds of garbage and large particles. It is important to knead just such an amount of solution that will be used in the next two hours - just such a plasticity period of this composition.

• Using a concrete mixer, the ingredients should be gradually mixed into the composition in the following order: water, cement, sand and water residues.
• The components must be added gradually and kneaded for about 2 minutes, after which it is poured into the container for further use as intended.
• During the masonry, mix the mixture periodically to ensure uniformity.

Some cases suggest the use of lime for the preparation of masonry mortar. This composition is characterized by increased ductility. The time of possible work with such a solution increases to 5 hours.

This is very convenient, since it is possible to procure a sufficient amount in advance so as not to waste time on manufacturing. However, for masonry, which can be significantly affected by moisture, such a solution cannot be used.

Proportions for the preparation of cement-lime mortar:

• 1 part of cement and lime + 4 parts of sand (M25);
• 1 part of cement + 0.5 parts of lime + 4.5 parts of sand (M50).

A concrete mixer is used to form the solution. The ingredients are added gradually, starting with water. Then cement is added, then lime. Everything is thoroughly mixed and after that sand and the remaining liquid are added.

Some features

You can not prepare the solution with your own hands, but resort to the use of ready-made dry mixtures, which, when water is added, are converted into a masonry mortar. Such items can be purchased at specialized stores.

• For mixing, the same concrete mixer or construction mixer is used.
• The amount of water required for each preparation is indicated on the package.
• Mixing such formulations typically takes about 6 minutes. It is important to adhere to the recommendations for the use of each specific mixture and in no case add additional ingredients. Such amateur performance can adversely affect the quality of future masonry.

• For example, a porous, moisture-absorbing substrate will provide better strength of the masonry mortar, unlike a brick that does not absorb moisture well.
• It is important to monitor the homogeneity of the composition in the process of laying products, i.e. constantly stirring the solution.
• If necessary, you can improve the consistency using additional components. Crushed stone, sand and other additives can increase the density of the solution. The quantity and quality of additional components determine the basic properties of the future material.

Practice shows that self-prepared solution has better quality than purchased. This is due to the components used and personal control over the cooking process.

In addition, it is quite difficult to control the quality of the finished product sold, regardless of its price and manufacturer.

Masonry process

The use of masonry mortars is quite wide:

• walls of houses subjected to stress and external effects from precipitation;
• foundations;
• masonry chimney pipes;
• masonry walls made of concrete blocks;
• clinker brick masonry and more.

High-quality masonry requires compliance with certain rules when applying masonry material. It is important to maintain the thickness of the joints, which should be in the range of 10-15 mm for the cement and lime-cement versions.

• If the construction project provides for the subsequent plastering of the building, then the seams should not be completely filled, but 5-10 mm should be left for their subsequent filling with plaster. This is necessary to increase the adhesion of the wall and plaster.
• When plastering is not planned, the joints must be repaired with particular care.
• Before starting the masonry process, the brick must be cleaned of dust and dirt.
• During the hot period, you should hold the brick in the water before starting work. Such a measure will allow the brick to become saturated with moisture before direct contact with the solution, which will prevent premature drying of the material.
• If there was a break in work, then the finished row of masonry can also be moistened.

You can use ready-made mixtures or prepare the solution yourself. In any case, quality control of the raw materials used and adherence to the cooking technology are important. Good luck
