In those cases where, for whatever reason, it is not possible to fill in a monolithic foundation, we can consider the possibility of mounting the foundation of a building from concrete foundation blocks. In general, these are seemingly ordinary standard blocks, but with much greater moisture resistance and frost resistance.
The foundation block is a concrete product that has reached the maximum level of strength in a special form. Foundation blocks are produced serially, in accordance with GOST 13579-78. Such foundation blocks are used for the construction of various types of foundations, for example, foundation tape or piles (pillars).
The blocks for the foundation during manufacture have standard dimensions:
Width 200 mm
Height 200 mm
Length 400 mm
At the same time, the weight of one block is only 32 kg. Thus, the foundation block 200x200x400 is the optimal material in the case when for certain reasons it is impossible to use heavy construction equipment on the site.
The basis of the production of fundamental concrete blocks - mortar based on concrete. Into its structure enter additional components that give to ready blocks various functional characteristics. The following can be used as fillers:
Crushed stone (hard rocks)
Slag waste of metallurgy
For fundamental concrete blocks, the sizes of the fractions of additional materials are very important. They must not exceed 20 mm.
As for concrete, in the production of standard fundamental blocks are used:
The group of autoclaved concrete includes solutions based on gas silicates and aerated concrete . The main binding components in them are cement and lime. Heavy concretes are distinguished by increased density.
If it is necessary to provide products with additional clear geometric forms and to increase the strength of finished blocks, the addition of reinforcement elements is used.
On our website you can find contacts of construction companies that offer the service of an audit of construction work. Directly to communicate with representatives, you can visit the exhibition of houses "Low-rise Country".
Given the above, it is clear that the use of fundamental blocks is advantageous primarily in the construction of private buildings of small size. This technique significantly reduces material costs and time resources spent on construction. Work takes much less time, given the use of high-quality pre-finished materials.
