FIELD: manufacture of building materials.
SUBSTANCE: subject of invention are concretes used to manufacture of wall stones, blocks, slabs of interroom partitions as well as for cast-in-place concreting of building walls. Aerated light concrete contains, wt parts: Portland cement 1.0-1.11, fine sand 1.5-2.43, air-entrainment additive (oxyethylated alkylphenol) 0.02-0.03, light aggregate: coniferous sawdust fraction below 5 mm 0.11-0.22 and polystyrene granules 0.0-0.035, liquid glass 0.01-0.06, sodium silicofluoride 0.01-0.012, and water 0.70-0.86.
EFFECT: reduced average density and heat conductivity, and improved ratio between density characteristics and strength of concrete.
