METHOD OF PRODUCTION OF A POROUS FILLER

FIELD: construction materials industry; production of heat-insulating burdens and a filler of light concretes. ^ SUBSTANCE: the invention is pertaining to the field of construction materials industry and, in particular, to production of heat-insulating burdens and a porous filler of the light concretes. The method of production of the porous filler includes preparation of a mixture of a liquid glass water glass and an additive, production of a core and its coating with a mineral composition. At preparation of the mixture in the capacity of the additive use an amorphous silicon - tripoli powder or a diatomite, or a molding box, and additionally - a foamer of PB-2000 type at the following ratio of ingredients (in mass %): the liquid glass - 45-78, the indicated amorphous silicon - 20-45, the indicated foamer - 2-10. In the process of the mixture preparation it is making porous till it achieves the density of a foam-shaped mass from 100 up to 300 kg/m3 and the coating of the core exercise using powdery inorganic binding or argillous materials. The technical result is a decrease of density of the filler and simplification of the production process. ^ EFFECT: the invention ensures a decrease of density of the filler and simplification of the production process. ^ 1 tbl, 6 ex
