Concrete walls

Most often, monolithic concrete is used for the construction of walls, which differ in comparable ease. Use concrete blocks in the production of concrete blocks of various aggregates, from sawdust to brick combat. Cement, gypsum, lime and clay are the binding materials. The type of concrete directly depends on the aggregate.

The most used option is slag concrete. The most strong can be called blocks of metallurgical or fuel slag, with a slight addition of sand. No other impurities, clay, non -combatant coal, ash, there should be no earth. During the year, the slag is kept in the open air to reduce the content of harmful salts and undigested particles.

Consists of slag concrete of granules of various sizes. Moreover, if most of the slag has a large size, then the concrete comes out light and not durable. The predominance of small slag adds density, and this, in turn, increases thermal conductivity.

For external walls, the desired ratio of slag of large and small can be from 37 to 46. For bearing walls, it is better to use more dense concrete.

Pour walls with the help of a rearranged formwork knocked out of the boards, which is covered with a film from the inside and inserted spacers.
