FIELD: no-fines concrete production useful in drainage systems and curb construction building.
SUBSTANCE: claimed method includes mixture preparation containing of Portland cement, water and target additive in wing blender; blending of said mixture with dense coarse aggregate and subsequent laying of obtained concrete mixture. Said aggregate is charged into blender-capsulator, then mixture of Portland cement, water and target additives is fed, and cotreatment is carried out for 1-3 min. Claimed concrete mixture contains (mass %): Portland cement 5-15, said aggregate 82-88, target additive 0-1.0, and balance: water.
EFFECT: simplified technology of no-fines concrete; concrete of improved quality.
