Masonry mixtures: description, brands, masonry, preparation, calculation, photo, video.

All masonry mixtures existing today are a special type of building material that is widely used for masonry or wall cladding using individual elements, including various types of bricks. To make durable and high-quality masonry, it is necessary to take into account the characteristic features of the composition of different types of mixtures, correctly prepare the working solution and follow the application technology.

Brick laying mortar

Standard composition

High-quality masonry mixtures are special complexes that, when mixed with water, can form a ready-to-use, durable, elastic mortar with high performance characteristics, suitable for construction or finishing work. The components of dry mixtures, as a rule, do not differ much, and are presented:

• a binder, which can be either natural clay or cement;
• the main component in the form of fractionated sand or expanded clay concrete;
• solvent in the form of pure water;
• a variety of additional mineral components.

If there is a need to obtain a brick masonry mixture that optimally matches the color scheme with the masonry being performed, a variety of natural dyes and pigmenting substances are used.

Characteristics and advantages of ready-made compositions for bricklaying

Components

The main components of the mixture for laying bricks are: lime, cement, clay or gypsum, sand, water, additives. What role does each of them play? Cement, lime, clay and gypsum act as binders. They are responsible for hardening. Compositions that include one binder component are called simple, while two or more are called complex.

Most often, a cement-based masonry mixture is used for brick walls and houses. It is best to take cement grade M 400; in general, the higher the grade of cement, the lower its consumption. The cement has sufficient rigidity and strength. There are also lime, cement-lime and cement-clay mortars. Many people believe that cement mortar is better than others for any type of masonry, but this is not true. In some cases it will be too rigid and overly strong. Mixtures for bricklaying of other compositions have their own application characteristics.

Important! Portland slag cement is not used for construction in cold weather. A solution based on it at low temperatures turns out to be of poor quality. For walls that bear a small load, such as fences, interior partitions, use lime mortar

It shrinks slightly and has low thermal conductivity, that is, it retains heat well, but after hardening it becomes brittle. This limits its scope of application. It is also used to repair walls.

For walls that bear a small load, such as fences and interior partitions, lime mortar is used. It shrinks slightly and has low thermal conductivity, that is, it retains heat well, but after hardening it becomes brittle. This limits its scope of application. It is also used to repair walls.

To prepare such a mixture, crushed quicklime is used. The composition is made warm, it turns out to be more plastic than cement, and does not harden longer. A composition using lime and cement is used for various structures; its advantage is that it has better thermal insulation ability than cement.

The cement-clay composition is the least durable of those listed. It is used for working with stone, brick, ceramics, for example, for laying stoves. It has high frost resistance, is durable and cheap

To prepare it, it is important that the clay is cleared of impurities and foreign inclusions (stones, roots)

Sand plays the role of a filler; it increases the volume and improves the mechanical properties of the mixture. Sometimes other ingredients are used for this, such as gravel, expanded clay, and polystyrene granules. Usually they are used not for masonry, but for pouring mortars. The sand should be fine, without impurities (garbage, clay, soil, roots), it is best to use river sand. Bright yellow sand should not be used in facing masonry or for bricks with cavities.

Water is the most important component of masonry mortar. Many characteristics of the composition depend on its quality, therefore the requirements for water are specified in GOST 23732-2011. To prepare the solution, the water must be clean, with a temperature within 15-20 degrees.

Additives may include:

• plasticizers - they make the composition more plastic and easier to work with; they are necessarily added to the mixture for laying facade bricks;
• hardeners – accelerate the hardening (polymerization) of the mixture;
• anti-frost additives - do not allow the mass to freeze at sub-zero temperatures, giving it the opportunity to harden well;
• pigments - color the solution in the desired color; if you need to get a dark-colored mixture, you can use soot or graphite.

Options with various additives are more economical and easier to work with, so it is better to spend time and prepare a mortar for bricks with improving additives, and then make the masonry faster and with better quality.

Selection principles

The key task of the masonry mortar is to perform a connecting function between all elements of the structure being built, and the choice of mixture should be based on the mandatory consideration of the following principles:

• the composition of the working solution for performing work in summer and winter has certain differences;
• when choosing a mixture, it is necessary to take into account the location of the object, since underground and above-ground work is carried out using solutions of different compositions;
• laying with clinker bricks is carried out using a working solution of a special composition;
• When constructing stove or fireplace structures, the use of cement mortars must be excluded.

Masonry mixture: choice, cost

The type of binder component included in the standard solution allows you to determine the type of hardening, which can be either hydraulic or air. If there is one binder component, then we have a simple mixture represented by lime and cement compositions. The presence of several binding elements is a sign of a complex masonry mixture, which can have high ductility and successfully resist cracking under the influence of negative external factors.

When ready-made masonry mixture for bricks is needed

Preparation of masonry mixture based on dry cement

As a basis for the masonry mixture for bricks, you can use a solution of concentration M25 or M50. Here the proportion of cement to sand is 1 to 5 (1 part of dry cement will require 5 parts of sand).

If the masonry mixture will be used under the foundation (or for an overpass in the garage), that is, constant static pressure will act on the wall, then it is better to give preference to the solution under M25 and reduce the proportion of sand to the level of 3 to 1. The less filler and the more dry cement - the more durable the mixture will be in the end.

How to mix all the ingredients correctly? The best option is to use a concrete mixer:

Instructions for preparing cement mortar.

• first of all, load half the sand;
• add cement;
• load the remaining half of the filler;
• mix everything thoroughly;
• add water, dye.

It is recommended to pass both sand and cement through a sieve before use to remove small construction debris and insoluble impurities (glass, metal). Colored masonry mixtures must be mixed more thoroughly to ensure normal distribution of the contrasting component.

For laying clinker bricks, it is allowed to use a mixture with a large amount of sand (M100 or more). But you need to understand that the consumption will be significantly higher, because the solution also fills the internal voids of the monolithic block. For laying bricks under decorative cladding, it is better to use M50 or M75, also reducing the sand concentration to a ratio of 1 to 3-4.

Main types

Today, the initial parameters of the mortar make it possible to subdivide all masonry construction and finishing mixtures into several main types.

Types of mixtures for bricklaying

Dry masonry mixture

The main components that make up any masonry mortar are dry mixture and water. But the whole secret in creating a truly strong mixture lies in strict adherence to all proportions of materials and the sequence of addition.

Dry masonry mixtures vary in their scope of application, therefore the compositions differ, despite the same base. They can be divided into two main categories:

• For general use in construction. X is used in the construction of walls. The most common are M150 and M200 - based on these two types, almost every manufacturer creates their own version, but due to the addition of various additives, the final result (products) differ significantly in characteristics.
• Special purpose. Used for laying stoves, chimneys, and swimming pools.

White

As a rule, white masonry mixtures are used when facing or restoring the seams of structures that have been used for many years in a row. These mixtures contain not only standard high-quality cement, sand and water, but also plasticizers, as well as lime milk.

In addition to aesthetic properties, which are one of the main differences, the solution has excellent elasticity, strength and practicality.

In addition, it is white solutions that have the ability to retain water (97%), which is very important when facing - the brick finish will last much longer and will not lose its characteristics and qualities.

Cement-sand

This type of masonry mortar is the most popular for all types of construction and finishing work and is often used when working with silicate or ceramic bricks.

Cement

Due to their high strength and rigidity, cement mortars are in great demand in the construction of private houses and high-rise buildings.

Cement-clay

The quality of these mixtures largely depends on the thorough grinding and purification of the clay, which is added to this solution, from impurities. Such compositions are used for the construction of private houses and low buildings.

Cement-lime

Due to their high ductility and adhesion, these types of mortars are often used for laying silicate and ceramic bricks.

Limestone

This type of solution is rarely used, as it has a low level of strength, increased fragility and low thermal conductivity. It is used only in the construction of low-rise buildings and low structures.

Color mixture

Colored masonry mixtures

Cladding activities using bricks often involve the use of colored mixtures. Such compositions have certain advantages, and the standard composition includes fine-grained inorganic components in the form of lime or cement, water and colored fillers. The ready-made mixture is typically filled with a mineral dye based on iron oxide. The total volume of dyes should not exceed 8% by weight of the entire solution. A high-quality color mixture can be represented by the following main components:

• cement grade M500, which reduces the release of salts and gives the masonry optimal strength;
• fractional washed sand, eliminating the presence of clay and foreign impurities;
• mineral-type colored pigment components that provide sufficient resistance to adverse weather conditions for long-term use and give an aesthetic appearance;
• polymer additives that provide high strength and water resistance.

The use of color mixtures allows a harmonious combination of the color of the brick with the coloring of the seams. When making your own, you need to remember that to obtain light colors, only white cement is added, and to achieve a dark shade, gray cement should be added.

Ingredient Requirements

The question of how to properly prepare a mortar for bricklaying requires not only the precise addition of components, but also the correct selection of materials according to their characteristics. This is mainly about cleanliness.

The sand should have minimal organic and mud inclusions. The cleaner the better, the higher the technical characteristics of the solution. The same goes for water. But here, special attention is usually paid to the hardness of the latter, and its composition in terms of the quantitative content of salts. Therefore, for laying bricks they try to use tap water, possibly from wells and wells.

Independent calculation of consumption

Step-by-step calculation of consumption allows you to obtain the most accurate amount of solution with minimal errors. First you need to calculate the area of ​​the masonry, excluding the area of ​​door and window openings, and then calculate the amount of mortar per each cubic meter of area - a third of a cubic meter of mixture.

For example: the task is to build a one-story building, with a wall length of 15 m and a ceiling height of 3.4 m. There are seven windows measuring 1.8 x 1.2 m and a pair of doorways 2.1 x 1.3 m.

An independent calculation of masonry with an external thickness of 64 cm and an internal thickness of 25 cm will be as follows:

• determine the total volume of the external walls: (4 walls x 15 m x 3.4 m – 7 windows x 1.8 m x 1.2 m – 2 doors x 2.1 m x 1.3 m) x 0.64 m;
• determine the total volume of the internal walls: (42 m x 3.4 m – 5 x 2 x 1.3) x 0.25 m;
• we calculate the ratio of aggregates and binding components 4:1;
• calculate the amount of cement.

As a rule, the following proportions are used when mixing:

• one part cement;
• three parts of sifted sand;
• ½ part water.

To prepare the most common types of mortar, the following proportions of sand and cement are recommended:

• 5:1 for the manufacture of grade M25;
• 4:1 for the manufacture of grade M50;
• 3:1 for the manufacture of grade M75;

For example, to prepare M25 you need to mix 2 tons of sifted sand, 0.26 tons of M400 cement and add 350 liters of water. The ratio may vary depending on many factors, including soil and climatic conditions and the location of the work. Clinker facing bricks require compositions with increased viscosity. The strength of lime mortar can be increased using hammer slag. A properly prepared mixture spreads quite slowly.

Types of solutions and their applicability

The connecting link between brick blocks is a mixture of the binder component with filler and water. The most common are 4 types of solutions.

• Cement-sand. It is diluted with water, its proportions depend on the brand of cement and the method of laying. When hardened, this option is the most durable, but if the technology is deviated from, it is prone to cracking;
• Limestone - in it cement is replaced with quicklime; it is plastic, but is washed out by rain, so it is only suitable for installing internal walls;
• Mixed - cement and sand are diluted with liquid slaked lime (lime milk). The combination combines the best qualities of the first two options;
• With a plasticizer - a polymer additive is mixed with cement and sand (fraction 2 mm) to increase the plasticity of the mixture. It is easier to make such a solution from a dry construction mixture by adding water according to the manufacturer’s instructions.

Despite the composition, the requirements for the quality of the mixture are almost the same. All ingredients are cleared of lumps, the sand is sifted, and the liquid lime is filtered. To prepare the solution, first thoroughly mix the powder components, then slowly pour in cold liquid (20 o C) and mix thoroughly so that setting does not occur. The process is accelerated using a concrete mixer or a hammer drill with a whisk attachment.

Mortar consumption per cube of brickwork

How long does it take to prepare mortar for laying a wall? This is determined by several conditions:

• the skill of a mason;
• the structure of the brick block - products with voids take more mortar mixture;
• type of brick - hyper-pressed and facing silicate absorbs less mortar than ceramic or ordinary silicate with a rough surface;
• wall thickness.

The average consumption of mortar per 1 m3 of brickwork with a standard joint thickness (12 mm) is approximately 0.23 m3. Table 1 provides more accurate information.

Cement consumption for bricklaying

The composition of the mixture for constructing a brick wall varies depending on the quality of the original components, weather conditions, and the number of storeys of the building. To mix the ingredients correctly, you should know: a 10-liter bucket holds 14 kg of cement or 12 kg of sand.

1. Cement mortar is flexible in proportions. It is characterized by the degree of strength: the lower it is, the lower the required grade of cement and the lower its percentage (1 part to 2.5 - 6 parts of sand). For M400 cement the ratio is 1.3, for M500 – 1.4. The volume of water (on average 0.5 - 0.7 liters per 1 kg of cement) depends on the desired thickness of the mixture, the type of brick, air temperature - in the summer heat the solution should be more liquid. To increase its plasticity, experienced masons add a little washing powder or dishwashing detergent to the water. For 1 cubic meter of ready-made mortar 1.4, 410 kg of M500 cement and 1.14 m3 of sand are needed. Knowing that for 1 cubic meter of an ordinary wall, one brick made of a silicate block 250 x 120 x 65 takes 0.24 m3 of mortar, the cement consumption per cubic meter of brickwork is determined as follows: 0.24 x 410 = 98 kg. Accordingly, when using M400 cement (proportion 1.3) a cubic meter of the mixture contains 490 kg of cement, and 117 kg of it is consumed per 1 m3 of masonry.
2. Cement-lime mortar is suitable for use within 5 hours, and in the summer at +25 o - no more than an hour, so calculation is also desirable for it. For 1 cubic meter of mixture, 190 kg of cement M400 - M500, 1.5 m3 of sand, 106 kg of hydrated lime and 475 liters of water are required. For a cubic meter of masonry you will need an average of 46 kg of cement.

Consumption of cement for laying bricks during cladding

In this case, the developer is interested in how much binder mixture will be consumed per square meter of wall. This depends on the water absorption of the building material, the season of work, the hollowness and porosity of the blocks. The standards are laid down in SNiP 82-02-95, but the real numbers are always higher, so you should buy ready-made mortar or cement with a reserve.

To save on consumables, 2 factors should be noted:

1. the larger the dimensions of the brick, the less mortar will be needed;
2. The higher the % of voids and pores, the higher the mixture consumption will be.

From this point of view, it is optimal to use ceramic or silicate double bricks of sufficient strength. This choice will allow you to achieve savings of 20% of the mortar mixture. Table 2 shows comparative data on mortar consumption per square meter of wall.

Consumption standards

Depending on the thickness of the brickwork, standard standards for the consumption of working material may vary.

Composition tips

The most common grades used for brickwork are M50, M75, M100, M125, M150 and M200.

According to SP 82-101-98, when preparing mortars for brickwork, you need to focus on certain parameters. A tabular example of obtaining a cubic meter of working composition using a concrete mixer with a capacity of 200 liters.

SP 82-101-98. Preparation and use of construction mortars

SP 82-101-98

To increase strength, it is advisable to add a plasticizer, which saves about ten percent of cement. As a result, there is no delamination, and application of the composition becomes much easier.

If there is a need to paint, the pigments are first diluted in a small amount of warm water and then added to the first portion of the concrete mixer composition. Standard additives, such as modifiers, plasticizers and hardeners, must be added to the same portion. The correct ratio is always prescribed by the manufacturer of building materials on the packaging or in the attached instructions.

Universal option

Cement-sand mortar according to the recipe given below can be used in many construction works.

To make a solution, you first need to prepare all the ingredients: cement, sand, water, detergent, which plays the role of a plasticizer. Detergents such as dishwashing liquid or liquid soap are a cheap substitute for special additives. They increase plasticity; add them in the amount of 1 teaspoon per bucket of cement. The grade of cement should be M 400 or M 500, sand with a fraction of 2 mm.

The proportions depend on the purpose of the composition. A mortar of grade M25 with a 5:1 ratio of sand and cement is used for most work, but for critical places where special strength is required, for example, for foundations, plinths, grades M50 (with a ratio of 4 to 1) and M75 (3 to 1) are used. .

A solution of grade M25 is prepared as follows. 1 cubic meter is obtained from:

• 2064 kg of sand;
• 268 kg of cement;
• 340-350 liters of water.

Usually the dry ingredients are mixed first and then diluted with water, but you can do it differently. First, pour water into the concrete mixer, and then gradually add the dry ingredients. This sequence will allow you to better control the thickness of the mixture.

First, detergent is poured into the water poured into the concrete mixer. After stirring for a few minutes it will foam. Next, sand is poured.

Attention! First, only half of the sand is poured.

After sand, add cement and mix until smooth. Then add the remaining half of the sand and mix thoroughly again. As a result, the consistency of the mass should be like thick sour cream. Checking the thickness of the mixture is simple: if you run your finger over it, there should be a clear trace that does not blur.

After mixing all the ingredients, stir them for 2 minutes. After this, the mixture is ready for use. To prevent the cement from delaminating, it also needs to be stirred occasionally during work.

You should not prepare a lot of working mixture at once. Remember that within one and a half to two hours it begins to harden and becomes unusable due to loss of plasticity.

Features of traditional masonry

Technological processes and principles are based on certain key parameters, including masonry thickness:

• half a brick - thickness is 12 cm;
• in one brick - thickness is 25-26 cm;
• one and a half bricks - thickness is 38 cm;
• two bricks - thickness 58 cm;
• at two and a half - the thickness is 64 cm.

Types of brickwork

Ceramic building blocks are installed on a layer of special mortar or bed. The same mixture is used to fill the gaps or seams between the elements. The standard thickness of the aggregate should not exceed a centimeter. Specialists in the field of finishing and construction work practice several types of laying elements, but the most common and simplest is the chain construction of walls. The following masonry options can also be used:

• continuous type;
• with four-row ligation of seams;
• with an air gap;
• well.

The choice of construction method depends on the height of the structure, its purpose, quality characteristics and dimensions of the building material.

The nuances of preparing the mixture with your own hands

The mixing process is simple, but for large volumes of work you need to buy or rent a concrete mixer. To obtain a high-quality masonry mixture for bricks, careful preparation of the components is required, their use in proportions according to the requirements of the technology and uniform mixing. The products are placed on an exclusively fresh solution; this is taken into account when determining the volume of the batch.

Any lumps are unacceptable; sifting sand through a sieve is a mandatory step, no matter how clean it looks. The size of the fractions is limited to 3 mm; for masonry work it is recommended to buy river sand. Before mixing with water, the dry components are thoroughly mixed together. All materials used are prepared in volume for one batch; it is better to prolong the cooking process than to allow lumps to form from moisture.

Next, most of the water is poured into a concrete mixer and combined with dyes and hardeners or plasticizers (if any). After that, cement and sand are added to the bowl and mixed for another 5 minutes. The whole process takes no more than 6 minutes, the resulting mixture is completely poured out of the concrete mixer and consumed in the shortest possible time. If necessary, the remainder of the water is introduced in small portions (approximate ratio - up to 0.8 to the proportion of binder, but not more than 25% of the total volume).

The preparation of mixtures with lime or clay additives is carried out in a similar way, but taking into account the increasing proportion of sand. In this case, the binder is mixed in dry form (cement + fluff, for example) and introduced into the bowl, and only after mixing is added sifted fine sand. When mixing small volumes, the solution can be mixed with lime milk.

Calculating the required amount of masonry mortar is a complex process. Manufacturers of ready-made dry mixtures indicate approximate consumption subject to the recommended or minimum layer thickness (rarely met conditions). The indicator is given in kg, consumed per one standard size product or per 1 m2 of masonry. In theory, it is enough to multiply it by the number of bricks or the area of ​​the cladding, but in practice much more material is used, especially when working with porous or hollow blocks (up to 30% at least).

Approximate consumption rates for cement-sand mortar are from 75 liters per 1 m2 of masonry products with standard dimensions and joint thickness no more than 10 mm. An increase in the inter-masonry space by even 1 mm leads to unjustified cost overruns and an increase in the cost of construction work. For a more accurate calculation, a value such as the volume of masonry is taken into account: in 1 m3 the proportion of the mixture is 25-30%. The technology involves wetting bricks and wall blocks, this reduces consumption and eliminates the process of drawing out moisture.

Step-by-step instruction

It is important to note that it is necessary to lay elements, regardless of the parameters of the structure being constructed, from the corners, following simple technology.

Step 1. Take a couple of bricks and place them, maintaining a right angle, on the foundation base, checking the accuracy of the location with a building triangle.

Step 2. Lay the next pair of elements, and then lay two more on top of the resulting group of four bricks, allowing the next row to overlap the previous row.

Half-brick facing masonry

Half-brick brickwork

Step 3. Having drawn the area into three elements, you need to carry out the same work on the other corner, using the order and pulling the moorings, which will allow the rows to be oriented strictly horizontally. The lacing should be located approximately every 5 m, without sagging.

Laying corners using single-row dressing

Single-row masonry involves building the beginning of the outer wall, and then the inner one, after which the backfill is laid. Multi-row masonry involves arranging blocks in a mixed or stepwise manner.

Masonry technology - detailed instructions

Sand-lime brick laying

1. After preparing the foundation, in order to identify distortions in time, use a building level. If there are defects, they are leveled with cement. Now mix the mortar for sand-lime bricks and begin laying from the corners. The process is quite simple, especially with one brick. A cord or thread is secured to control the laying plane.
2. First, a mortar “bed” is prepared. The solution is applied to the base with a trowel, leveled and the excess is removed from the front side of the masonry. The brick is placed on the mortar, tapped, and leveled.
3. Next, the second and subsequent bricks are laid. In this case, the solution is applied not only to the base, but also to the end of the previous brick.
4. The second row of bricks is laid with dressing, i.e. shift the bricks halfway relative to the first row.

Bandaging walls made of sand-lime bricks looks like this:
When laying a wall of two rows of bricks, you need to remember that bandaging is also necessary between the walls. To solve the problem, you can lay bricks transversely in every second row. This way they will connect all the stones. Coincidence in rows of seams is unacceptable. The second way of dressing is to turn several bricks standing in a row crosswise in every fourth row. Both of the above methods are used alternately if the complex masonry consists of three rows.

Rules for applying the solution

Today, in modern brick construction, several effective methods of applying working mortar are used. When laying it yourself, it is enough to choose the most convenient option.

First way

Step 1. Lift the element previously laid on a dry surface with your left hand.

Step 2. Using your right hand, apply the solution to the installation area and use your fingers to level it to the optimal thickness.

Step 3. With your left hand, lower the brick into the water and place a small amount of mortar on the side.

Application of the solution

Step 4. Place the element on the “bed” and press, slowly moving back and forth, which helps to obtain a thin seam.

The order of operations when laying end-to-end is as follows

Second way

Step 1. Place the element on the working solution distributed over the surface.

Step 2. Raising the back of the brick, lower its front side so that the forward movement causes the mixture to be set with the butt edge.

Step 3. With both hands, push and press the brick against the adjacent element, squeezing out the excess amount of mortar.

Third way

Step 1. Gently but thoroughly wet the brick in warm water.

Step 2. Apply a heap of solution to a well-moistened surface.

Step 3. Apply the mixture to the end part, then lay the brick and press it, moving it back and forth with both hands.

Walling

The use of colored solutions to mask masonry seams

In addition to contrasting the line of brick laying, a colored binder can be used to completely hide the structure of the wall. At the same time, the mortar joint itself has an absolute color match with the color of the facing brick. When the seam is cleaned, it is leveled flush with the bricks and, after drying, even follows its texture. The wall may look like a monolith or have a completely different pattern, a larger grid of blocks made of several bricks, or specifically outlined and shaded.

And often this is not a whim of the artistic imagination of the home owner. Experts recommend a similar technique to increase the thermal insulation characteristics of walls. In addition, the main problems with cracking of beautiful ceramic bricks are associated with the intensive absorption of moisture by the masonry through the mortar joint recessed into the wall.

The leveling technique is effective, but requires considerable effort and knowledge in accurately selecting the composition of the colored binder. As the colored seam dries, it lightens. Moreover, under the influence of the sun and rain moisture, part of the coloring pigment may fade, which is why a thin mesh of the seam appears against the background of the wall, but clearly visible from a distance.

Tips and tricks

The laying of every third or fourth row must necessarily end with filling the seam space, which will make it possible to obtain more attractive seams, and also help to increase their resistance to temperature changes. Among other things, such an event is aimed at a kind of prevention of destruction of the structure as a result of the negative effects of moisture. The only option when it is permissible to neglect such a procedure is to finish the wall with plaster.

It should be noted that it is necessary to control the quality of installation almost constantly, and each square meter of the constructed surface must be checked for the correctness of corner connections, vertical and horizontal indicators using a plumb line, building level and square. It is strictly forbidden to shift the laid elements after the solution has hardened.
