FIELD: construction.
SUBSTANCE: invention relates to production of construction materials and can be used in making cement for various purposes with additives. Method of recycling wastes from production of magnesium silicate proppant, which represent dust carry over burning serpentinite, require dust formed when granulation, drying, grading and firing of raw proppant, as well as sinter formed during roasting raw proppant, said wastes are entered in Portland cement as functional technogenic mineral additive in amount of not more than 20 wt%, wherein sinter formed during roasting proppant-chopped, first ground to particle size of less than 30 mqm.
EFFECT: technical result is environmental protection and high strength of cement.
