METHOD OF MAKING ARTIFICIAL POROUS AGGREGATE Russian patent published in 2011 - IPC C04B20/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of artificial porous aggregates for concrete. The method of producing artificial porous aggregate involves laying granular material into two layers, sintering, grinding and fractionation, wherein the granular material used is glass and/or frit with particle size 1-10 mm, mixing with liquid glass in amount of 10-30% of the weight of the glass and/or frit. The layers are 6-30 mm thick and a 1-10 mm thick intermediate layer is placed in between them using chalk and/or dolomite and/or gypsum dihydrate which is ground to particle size 1-5 mm.

EFFECT: high efficiency of the method.
