FIELD: chemistry.
SUBSTANCE: in the method for producing epy activated organomineral powder for bitumen-concrete mixtures, the co-milling of silica gel and ash-and-slag wastes is carried out in the ball mill. The selection from the produced milled material of the working fraction with a size of 0.07-0.31 mm is performed, the said working fraction is loaded into the mixer, in which also the slaked lime is loaded, and intermediate mixing is carried out. Then, a hydrophobic surfactant is loaded into the mixer in amount of 0.3-0.5 wt % of the slaked lime and final mixing is carried out until the homogeneous mixture is produced.
EFFECT: increasing the ecological and economic efficiency of producing activated organomineral powder.
