FIELD: mortar solutions for manufacture of brick and other building materials. SUBSTANCE: molding mixture for manufacturing building structures is essentially homogeneous suspension of silicon dioxide particles in colloidal solution of silicic acid the solid phase of which constitutes 90-95 wt% and contains 7 weight parts of natural quartz sand, two weight constitutes 2% of average particle size of natural quartz sand used, and one weight part of amorphous silicon dioxide having average particle size which constitutes 16% of average particle size of the same quartz sand. Use of the molding mixture makes it possible to manufacture cheap products. EFFECT: improved properties of the molding mixture. 1 tbl
