FIELD: construction and finishing works, particularly concrete articles, decorative panels, road and pavement coverings.
SUBSTANCE: composition comprises cement, crushed stone, sand and plasticizing agent. Cement-sand mix in previously treated in disintegrator to obtain 1-8 μm particle dimensions. The plasticizing agent is oil-containing mud. Above components are taken in the following amounts (parts by weight): M500 cement - 280, sand - 260-720, crushed stone - 1000, oil-containing mud - 100-560, water - 150 or M200 cement - 450, sand - 100-560, crushed stone - 1000, oil-containing mud - 100-560, water - 150.
EFFECT: decreased high-grade cement consumption, possibility of used concrete article or low-grade usage for paving slab production, decreased time of design strength development, reduced hardening chamber area and increased mold rotation.
