FIELD: building materials, in particular polystyrene-concrete foam articles.
SUBSTANCE: claimed method includes mixture forming in the next component ratio (mass %): Portland cement 81.0; granulated foamed polystyrene 4.0, wherein three parts thereof have granule diameter of 1-2 mm, and one part has granule diameter of 2-3 mm; plasticizing additive 0.5; air-entraining admixture 0.02; and balance: water. For mixture production 2/3 of Portland cement, both additives and 1/2 of tempering water are charged into mixer and agitated for 2-3 min. Foamed polystyrene having granule diameter of 1-2 mm, is added and agitated for 1-2 min; remained cement, foamed polystyrene having granule diameter of 2-3 mm, and remained water are added and agitated for 2-3 min. Mixture is placed into curb, floated and conditioned at 20°C for 8 hours. Finished articles are laid in stacks for storage or hauling.
EFFECT: building articles of increased heat insulating properties, improved constructive characteristics and decreased average density; simplified technology.
