Rubble stone

Material is applied in the field of construction. For a laying of the base of the building, walls, roads. Stones weighing less than 5 kg are not used, the bulk of the used stones has to weigh from 20 to 40 kg. Existence of cracks, traces of aeration, friable clay components will lead to reduction of a stone in volumes. Such process arises because undesirable inclusions are capable to be dissolved, softened and dry. It is easy to determine a level of quality by the hammer. If the stone qualitative, then at blow a sound turns out ringing. If the sound hard of hearing, then this direct evidence of availability of undesirable impurity is heard. At blows of stones weighing about 1 kg the piece will turn into crushed stone. Application of a rubble stone is pertinent in a rubble and butobetonny laying.
