FIELD: manufacture of building materials; manufacture of lime-and-sand bricks and wall items: tiles, blocks, wall panels. ^ SUBSTANCE: proposed raw material mixture contains the following components, mass-%: lime-and-sand binder, 29.5-32.6; silica component, 10.5-57.4; ground cellular glass, 10.0-60.0. Building items in form of blocks, plates and panels on base of silicate material of autoclave hardening contain the following components, mass-%: lime-and-sand binder, 29.5-32.6; silica component, 10.5-57.4; ground cellular glass, 10.0-60.0. Items made from this raw material mixture retain density, heat and sound conductivity. ^ EFFECT: low cost of wall items at retained strength. ^ 3 cl, 1 tbl, 1 ex |
