FIELD: construction.
SUBSTANCE: hollow building block, which has two side and two end walls, and at least one link parallel to end walls, which separates the block cavity. Its hollowness makes from 20% to 60%, and it is made of a mixture, which contains cement, swollen perlite sand, a solid filler with hardness of at least 1.25 and water with the following content of components, wt %: cement of grade 400 or 500 - 38-42%; swollen perlite sand of fraction 0.63…5 - 12-15%; solid filler of fraction 0…5 or 0…10 - 32-38%, water - 14-17%.
EFFECT: invention provides for strength without loss of heat insulation and weight characteristics of perlite concrete, reduced load at structures during cast-in-place concrete house building.
