FIELD: foundry work. SUBSTANCE: mixture has, wt. -% : ortho-phosphoric acid 1.8-2.6; hardener in the form of magnesium-containing material (metallurgic magnesite powder) 0.9-1.3; modifying agent representing product of oligohydroxymethylhydride silmethylenesiloxysilane synthesis with a mixture of products of vat residues esterification with ethanol from direct synthesis of methylchlorosilanes 0.2-0.3; refractory filler of silicate nature in the form of quartz sand, granular zircon or disthene sillimanite - the rest. The presence of modifying agent in mixture provides high strength properties at initial and final phases of its hardening. Mixture does not weaken in humid medium. EFFECT: improved method of making, enhanced quality of mixture. 2 tbl
