COMPOSITION FOR MAKING POROUS AGGREGATE Russian patent published in 2018 - IPC C04B14/24 C04B20/06 C04B38/00 

FIELD: construction.

SUBSTANCE: invention relates to production of construction materials, particularly to production of porous aggregates based on liquid glass, meant for making light concrete, as well as fill insulations. Composition of a porous aggregate production includes, by mass%: liquid sodium glass with the density of 1.41 g/cm³ 50–75, sodium chloride, ground to a size of less than 0.3 mm, 1–3, shale coke, ground up to pass through a 0.14 mm sieve and containing, mass%: SiO₂ – 28.6; Al₂O₃ – 6.7; Fe₂O₃ – 5.4; CaO – 21.5; MgO – 2.2; R₂O – 3.5; pp. – 32.1, 22–49.

EFFECT: increase in compressive strength and softening factor of porous aggregate, industrial waste utilization.
