FIELD: chemistry.
SUBSTANCE: invention relates to production of porous filling agents for concretes. Charge for production of porous filling agent contains, wt %: montmorillonite clay 87.0-87.5, coal, milled to specific surface 2500-3000 cm2/g, blastfurnace slag, milled to specific surface 2500-3000 cm2/g 3.0-3.5; quartz sand 4.0-6.0, milled to specific surface 2500-3000 cm2/g, halite 0.5-1.0, soda ash 0.3-0.5.
EFFECT: increase frost-resistance of porous filling agent, obtained from charge.
