FIELD: construction material industry. SUBSTANCE: method involves introducing cement, superplasticizer in an amount of 1.2-20% by weight of cement, 20-60% by weight of total amount of sand and water into high-speed mixer and mixing at peripheral speed of 5-20 m/s for 10-75 s; mixing obtained solution with remaining sand and large-size filler till homogeneous mass is obtained. Viability of concrete mixture is 60-120 min. EFFECT: increased viability of concrete mixture and reduced consumption of cement, with strength being retained. 1 tbl
