Concrete blocks for the foundation - constructive types, specific application

Concrete blocks for basement

Laying the foundation - the question of responsibility. After all, the strength of the foundation depends on the strength of the building. This is the foundation of the building, she bears the greatest burden. It provides stability and rigidity. For laying the foundation necessary to use durable materials, resistant to frost, moisture, a destructive action of microorganisms. Concrete blocks for basement - that kind of stuff.

What are these blocks for the foundation

foundation blocks - Secondary products of concrete, and high strength,they are intended for the construction of the tape and columnar foundations. This versatile design can also be used for the construction of basement walls, basement and technical rooms, garages. Concrete blocks for the foundation must be resistant to temperature changes, strong, durable. concrete grade M-150 is most commonly used for the manufacture of blocks, M-100, M-200. Depending on the concrete class by the presence of the reinforcing frame, and the used technology foundation blocks distinguish varying degrees of resistance to mechanical stresses and adverse environmental effects.

Laying the foundation - the question of responsibility. After all, the strength of the foundation depends on the strength of the building. This is the foundation of the building. It carries a heavy load. Passing on the ground. It provides stability and rigidity. For laying the foundation necessary to use durable materials, resistant to frost, moisture, microbial action. Concrete blocks for basement - that kind of stuff.

Concrete blocks for basement - secured home base strength

There are many characteristics that distinguish concrete blocks: compressive strength, frost resistance, water resistance, water absorption.

Choosing the best option depends on theclimatic conditions, from the shrinkage of moisture and soil density. One of the main criteria for the selection of the foundation block is a boundary load that pripadet the foundation.

Three types of basic units

  • FBS - solid foundation blocks;
  • FB - solid fundamental blocks with cutout for laying of jumpers and communications;
  • FSF - hollow ( "U-shaped"), foundation blocks.
FBS, and NDF

Solid and hollow blocks - structural differences

Solid foundation blocks - the mostcommon, are made of heavy concrete or high density silicate concrete. They are a key element tape and columnar foundations. This unit is strong enough and has a high density, so it blocks PBS used as a base in the supporting structure; such blocks are used for the building of high-rise and low-rise construction of private homes. In addition to use as a base, can be applied to the construction of the wall in the basement of the building.
Hollow concrete blocks are used aspermanent formwork. In the construction process the voids are filled with concrete in the blocks. The blocks are designed so that the horizontal joints were reinforced. Prior to filling the voids inserting reinforcement bars, which provides additional structural strength. Fundamental walls built from hollow blocks with voids filled with concrete, have increased compressive strength, and enhanced vertical reinforcement also have improved strength at lateral loads.

Hollow blocks come in various sizes, the most frequent 51:40:25, 51:20:25 and 51:25:25.

To facilitate communications,using basic blocks with special cutouts for tech communications. Used classic (heavy) concrete blocks and lightweight - lightweight aggregate.
Concrete blocks for the foundation is made of expanded clay, concrete, as well as high density silicate concrete.
Lightweight aggregate blocks have goodinsulating properties, but also high water absorption - is extremely important to carefully basement waterproofing. The foundation of expanded clay concrete blocks can be build only in the absence of high-level groundwater. Lightweight aggregate blocks easier and cheaper. They are ideal for foundation for the garage or bath.

The house with heavy walls (brick, stone, cinder block) it is advisable to build on a foundation of tape blocks FBS. The foundations of columnar type of concrete block is ideal for a wooden building.
Concrete blocks used for the laying of foundations of buildings of any and all types of assignments.

Design variations blocks for the construction of foundations

  • F - reinforced concrete (reinforced), concrete and heavy concrete;
  • FBS - solid, reinforced;
  • FL - reinforced concrete (reinforced), used to strip foundations;
  • BF - reinforced concrete, heavy concrete;
  • FSF - hollow;
  • FR - reinforced concrete, heavy concrete for trehsharnirnyh frames.
Different size, shape and weight of concrete blocks. For high-rise buildings need large blocks, for low-rise is much smaller.

Different size, shape and weight of concrete blocks. For high-rise buildings need large blocks, for low-rise is much smaller.

Wall blocks sectional formquadrangle, some blocks are made with additional cutouts. Used such blocks for underground and above-ground part of the foundation. Pillow Blocks - trapezoidal shape (to increase the bearing surface) are used for laying the foundation of the first row.

Concrete blocks for the foundation area product of factory production, which means guaranteed quality and identity characteristics of all the concrete blocks of the same brand. Application foundation blocks can significantly reduce the amount of concrete and cement works, and therefore substantially reduce the cost of construction.
