COMPOSITION FOR POROUS AGGREGATE PRODUCTION Russian patent published in 2017 - IPC C04B14/24 C04B20/06 C04B38/00 

FIELD: construction.

SUBSTANCE: composition for porous aggregate production includes, wt %: sodium liquid glass with the density of 1.41 g/cm³ 50-75, sodium chloride milled to the size less than 0.3 mm, 1-3, burnt rocks ground to pass through a sieve 0.14 mmformed after the spontaneous combustion of oil shale with the oxides content, by wt%: SiO₂ - 38.4; Al₂O₃ - 17.18; Fe₂O₃ - 7.8; CaO - 11.13; MgO - 0.8; R₂O - 1.5; LOI - 23.19, 12-34, gliers ground to pass through a sieve of 0.14 mm with the oxides content, wt %: SiO₂ - 61.5; Al₂O₃ - 19.8; Fe₂O₃ - 7.4; CaO - 6,7; MgO - 2.2; R₂O - 1.1; LOI - 1.3, 10-15.

EFFECT: increasing the compressive strength and the softening coefficient of the porous aggregate, industrial waste recycling.
