Constructional materials

the Brick can be clay - red, silicate - white, shamotnyj — yellow. On a way of manufacturing it shares on integral, perforated, hollow. The red brick is widely used for a laying of walls, internal partitions, columns, and also the bases and to oven works. The red brick in length 250, width 120, thickness of 65 mm is issued. The normal red brick should not have a yellowish shade (nedozhzhen) or the melted off surfaces (it is burnt through, suits the base), the sound at blow should be pure.

The Silicate hollow and perforated brick is used only for a laying of walls, internal partitions, columns Silicate has first two sizes the same, as red, and on a thickness it can be one-and-a-half and double. The unary silicate brick weighs from 3,5 to 4 kg, one-and-a-half - about 5 kg, double is issued with emptiness and weighs about 5,7 kg.

Shamotnyj a brick shares on fire-resistant and refractory, it together with the best red is applied at oven works and serves several times longer. The fire-resistant brick in the sizes 250x123x65 mm is issued, weighs 3,4РєРі, refractory, at the same sizes on 0,5РєРі it is easier.

At all kinds of a brick the correct form, direct edges, absence of cracks is important.

Cellular concrete is much easier than a brick, provides approximately on 20% the best thermal protection, is easily processed, building will manage to you of percent on 15 more cheaply. Application of cellular concrete provides indoors the good microclimate close to that is available in wooden houses.

the stone is used by Butovyj at building of the base as a filler of concrete and is pieces of limestone or sandstone in weight no more than 50 kg. The stone should be without cracks, stratifications, to be applied by the pure.
