Every person who is at least a little familiar with construction knows that the price of thin concrete is significantly lower than that of heavy concrete. The reason for this is the low cement content, the share of which in the total cost of the solution is about 70%. But the share of the cheaper component – filler, on the contrary, has been increased.
For many construction work It can be much more profitable to buy lean concrete inexpensively, since its functional characteristics are quite sufficient, and there is no point in overpaying for expensive cement. This approach is especially effective if a large volume of building material is needed, for example, when preparing the foundation during road construction.
We have increased the removal of mastic, rubber and putty by more high level! Includes degreaser oil concentrate for complete performance. First, the carpet, mosaic and other materials covering the floor are removed. You'll be amazed at how the putty becomes so soft you could scrape it off with a putty knife! All that is needed for cleaning is a rinse with a degreaser and water.

However, the low cost of lean concrete is not its only advantage; we can list several more significant advantages of this building material:
- good physical and mechanical properties;
- high rate of hardening compared to more plastic mortars, which makes it possible to reduce the duration of construction work;
- the possibility of producing the mixture directly on the construction site;
- high degree of material homogeneity;
- ease of installation - the material is easily and quickly rolled with a road roller.
Depending on a number of parameters that characterize lean concrete, its price can vary significantly. Such parameters, in particular, include the brand of the mixture, the size of the fractions of the aggregate used, frost resistance, mobility, and so on. Thus, for lean concrete B 7.5, the price per cubic meter will be slightly lower compared to grade B 12 5. The first option has lower strength characteristics and is usually used as a leveling (roughing) layer.
Don't know how many layers to remove? That is, three times more than most traditional removers! Applying a thin layer may reduce labor or not work. The rule we use is "the heavier or thicker the rubber, you should let it rest more." For most, it's best to let it sit for 8-12 hours, but when there are two layers of rubber, as multiple floor-to-floor applications can take up to 24 hours.
Asphalt pavement refers to any paved road with asphalt. The resulting hot mix asphalt is loaded onto trucks for transportation to the paving site. The asphalt is placed and then compacted using a heavy roller that is driven over the asphalt. Traffic is usually allowed onto the sidewalk once the paving has cooled. The end result is a stronger, better-looking finish that improves the ride quality for drivers and reduces traffic noise for the community.
In addition, a distinction is made between fine-grained and coarse-grained lean concrete. The main criterion is the maximum size of the crushed stone fraction - up to 5 mm for fine-grained and up to 40 mm for coarse-grained mortar.
If you need high-quality lean concrete with delivery, you can buy it at MirBeton LLC. Our company is a direct manufacturer of building materials, so the cost of products is always at an acceptable level. Concrete delivery is carried out by specialized vehicles throughout Moscow and the Moscow region.
This minimizes delays for motorists and allows construction to occur during off-peak hours. Rubbilization with asphalt surfacing is a very cost-effective rehabilitation method. For initial construction and over the long term, asphalt pavement saves money on construction and maintenance. This is the conclusion of highway engineers and transport departments throughout the country.
Motorists care about smooth sidewalks. Asphalt will continually provide the public with the smooth, quiet ride they expect. Smooth sidewalks save transportation costs. Asphalt sidewalks are smoother and can withstand smoother surfaces more easily than concrete sidewalks.

Skinny concrete is construction material, in which significantly (relative to the volumes of components ready-mixed concrete) the proportions of cement and water are reduced, and the content of filler (crushed stone, gravel) is increased. It got its name because of the small amount of binder included in the mixture, but such concrete should not be classified as defective products coming out of concrete mortar units. It is used in construction in cases where the use of ready-mixed and rich concrete is impractical. This leads to significant savings on the most expensive component of the concrete mixture – cement. In addition, the reduction in price of products is facilitated by an increase in the volumetric content of inexpensive crushed stone in it.
A national survey found that drivers prefer well-maintained, safe, and smooth roads; In addition, they understand that these qualities require periodic maintenance and financial investment. Underlay: The base or support for the floor.
The amount of water in the mixture and stages of implementation. Water must be strictly necessary and the solution must be spread in small dense layers if the thickness to be covered is more than 2 or 3 centimeters. For walk-through or machine sheds, it may sometimes be necessary to construct a reinforced subfloor. Ability to absorb natural movements of the structure. Table 11: Countertag thickness depending on use. Purpose of Use Interior Residences Interior areas of buildings, sidewalks or sidewalks, and areas where large animals, tractors, or heavy loads do not pass.
The use of lean concrete in construction helps to significantly reduce cement costs.
In addition, lean concrete prepares and hardens much faster, which can significantly speed up the work. Hydration processes after laying lean concrete proceed faster due to the minimum amount of reagents (cement and water). Because of this, the lean solution retains its technological characteristics longer after preparing the mixture, so it can be used for pouring structures for a longer time than ready-mix and high-fat concrete. It is worth noting that the latter circumstance allows the concrete solution to be transported over long distances, although it is quite simple to prepare it directly at the work site.
External areas with transit of small vehicles, areas where animals are kept. Parking areas for equipment, tractors and heavy vehicles. To prepare the base, the following steps must be followed: - After cleaning the base and removing any remaining debris from the mortar, debris or any material on which the first step is applied, the level should be transferred using a hose level from the reference level. - Mark the height of the floor using tape. On clean surface throw the water and glue mixture into the area where the talisque will be made.
Properties of lean concrete mixtures
However, there are restrictions on the lower limit of the content of the binder component in the solution, beyond which the manufacturer will receive a mixture that crumbles at the slightest load. Cement in the solution should not be less than 5% of the total volume of the mixture. This rule is enshrined in SNiP. The same standards regulate other characteristics of concrete:
After leveling the solution, place the talisk. Using a path and anticipating cutting in the direction of the drains, in accordance with the project, check the level height flooring. With the string taut, check the height 49. Then sprinkle cement all over the base. Using a brush, brush the entire area. Use a hoe to fill in the gaps between the talismans, spreading the mortar in a motion so that it doesn't dry out too quickly. The solution must be sealed with a wooden rosette. This process must be carried out until the flooring solution reaches the level indicated by the wire.
- class (skinny compounds belong to classes from B 5-B 15);
- brand (M 75, M 100, M 150, M 200);
- frost resistance class (F50-F100);
- waterproof class (from W2 to W4).
Products made from lean concrete when tested can withstand loads from 5 MPa to 15 MPa (from 50 kgf/cm 2 to 150 kgf/cm 2), belong to grades from M 75 to M 200. They do not collapse during 50-100 freeze-thaw cycles and are capable of not allowing water to pass through, exerting a pressure of 0.2 to 0.4 MPa on their surface. These are not very high figures, but best characteristics are not required from lean mixtures (more details about the areas of their application will be discussed below).
Remove the remainder until the surface reaches the level of the stripes on all sides of the base area. Work the dough, smooth it out and give the final finish when working with a wooden spatula. The underground solution usually has the following trace and exit. Table 12: Base Solution Tracking and Yield. Before producing lean concrete, the soil must be wetted. Care for preparing the base: - Make concrete in alternating rectangles - Placement of planks between rectangles - Know the side and horizontal slopes beforehand.

Areas of use
So, lean concrete is in demand for the following stages of construction:
- installation of a base for the construction of a roadway (but to increase the water resistance of the solution, appropriate modifiers are added to it);
- laying the base for strip, slab and pile foundations;
- sealing holes in elements;
- installation of various screeds that are not exposed to moisture;
- pouring rough foundations before installing pool bottoms or floor slabs on the ground.
The main task of lean concrete is to stabilize and strengthen the soil on which the structure will be built. Most often, mixtures of grade M 100 or M 150 are used for these purposes, but concrete grade M 200 can already become a material for the manufacture of interfloor ceilings, lintels, stairs, balustrade posts, blocks and slabs.
Figure 44: Concrete deck system. 50. Table 13 shows footprints and yields for some types of flooring that may be used in rural buildings and structures. Table 13: Tracking and yield of various flooring solutions. Cement tiles Tiles and ceramics Tracing - 1 can of cement - 3 cans of sand - 1 can of cement - 3 cans of sand - 1 can of cement - 1 ½ cans of lime - 4 cans of sand Output per bag of cement 50 kg 4 m 2 Tip Smooth cement is the most economical floor covering.
It can be burned with cement powder and painted with dye powder. For grouting tiles and ceramics, use cement paste, but wait one day for the 7m2 high grout to dry. It can be built into a lying brick which provides good conditions thermal insulation. It should have a cross slope of 2% from the center to the ends of the enclosure and be at least 20cm above the adjacent ground without drainage as it allows the introduction of small rodents and unwanted insects. Scaffolding Use a material that can absorb moisture from bird feces.

Composition and proportions of mixtures
Since the technology for producing lean concrete is simple, it can be prepared directly on site. You need to remember that you should not add water to the solution until it reaches a creamy consistency. Lean concrete should be brought to a state reminiscent of damp earth. Lean mortars have low plasticity, and their hardness increases with decreasing grade. This property allows them to lay concrete mass during road construction using a roller. The same circumstance prevents pouring low-grade solutions into narrow molds.
Promote floor thermal insulation, avoiding birds' heat loss, mainly in the initial phase. 51. Peel rice, peanut shell, coffee husk and others. Healthy Bird The floor can be partially torn, and the male and spare boxes can accept a compact or partially cut floor. A rough floor can damage the animal's body, and an overly smooth floor makes it difficult to climb and lie down. At the rear of the bays, a waste collection channel is built with a slope sufficient to ensure that no waste remains inside it.
Maternal parietal cells should be placed at floor level. Figure 45: Floor type for pigs. Figure 46: Bay types for pigs. Full slatted flooring is best for hot regions but is the most expensive. Partial lattice floor: consisting of 30% of the bay floor area in a lattice on a pit, made of concrete beams, and the rest of the compact floor area in concrete. Waste management should be outside the building and room to ensure greater hygiene and cleaning.
Lean concrete can be fine-grained or coarse-grained. The type of concrete mixture depends on the crushed stone fraction. Filler consisting of pebbles 5 mm in diameter is poured into the fine-grained one. Coarse-grained concrete is prepared from crushed stone of 40 mm fraction. The water in the mixture should be 20-30% less than cement if it is produced with fine filler. With coarse-grained crushed stone, the amount of liquid for making concrete increases, since the filler will absorb part of it. However, the water content of coarse concrete should not exceed 85% by volume of the binder component.
The slope of the bay floor should be between 3% and 5%. Plastic floors can be used in refrigerators, pig boxes, food storage, and wet floors. The material used is high density polyethylene added to resist solar rays. Increase the value, comfort and safety of the building.
Preforms are the most economical and easiest to implement. 53. They consist of beams or concrete beams and blocks, which can be of different materials, the most commonly used being ceramic and concrete. Precast Slabs - Suggested Slabs - General Slab - Lattice Slab General Slab The beams are inverted T shaped and have internal steel bar reinforcement. The blocks or tiles are predominantly ceramic with an average width of 32 cm. The slab is assembled by intercalating tiles and beams, to which is attached a layer of concrete, called a cap, cast into pieces.
When using M 400 cement to prepare concrete M 100, the ratio of components will look as follows.
If a binder of grade M 500 is used, then the amount of sand and crushed stone in it increases significantly.
You should know that 10 liters of M 400 yield 78 liters of M 100 concrete, and 10 liters of M 500 yield 90 liters.
Grade M 100 is the most popular grade of lean concrete for foundation preparation work, however, grades M 150 and M 200 are used for the manufacture of more critical structures. Their composition is given in the following table.
Trolled slab. It has armor as a metal structure called a truss, which is fused with concrete base, forming a vigota. They usually consist of ceramic blocks and can also be used concrete blocks. Part of the armor from the beams is exposed, which favors adhesion after the concrete has started running. For small jobs with spans up to 5m, as cladding should be 8cm thick, with 8cm trusses, or as floors should be 10cm thick, with 8cm trusses. Can be used for large spans.
Common beams Trellinated beams Figure 48: Spacing for beams on masonry support. It is not recommended to crimp a masonry wall slab without a beam or fastener due to the low resistance of brick and the brittleness of hydrated lime installation mortars.
The corresponding yield of finished concrete is:
- 64 l;
- 73 l;
- 54 l;
- 62 l.
