FIELD: manufacture of building materials. SUBSTANCE: process involves preliminary common grinding of (wt %) Portland cement (14.7-22.5), quartz sand (1.7-2.5), and superplasticizer (0.22-0.34) until specific surface 4500-5500 qu.cm/g is attained, followed by mixing ground product first with nicrosilica (0.7-1.1) and then with mortar sand (22.56- 82.68) or its mixture with crushed rock fraction 5-20 mm (0-51.0). EFFECT: increased bend and compression strength of products. 1 tbl
