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. In the method, the composition for the production of porous aggregate includes, wt.%: sodium liquid glass with density of 1.41 g/cm³ 50–75, sodium chloride, ground to a size of less than 0.3 mm, 1–3, shale coke with oxides, wt.%: SiO₂ – 19.4; Al₂O₃ – 9.8; Fe₂O₃ – 3.4; CaO – 29.8; MgO – 1.8; R₂O – 3.6; percentage of other impurities– 32.2, 22–49.

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