FIELD: chemistry.
SUBSTANCE: invention relates to construction materials and can be used as a complex additive in a solution mixture during production of foam concrete. Complex additive for foam-concrete mixture contains, wt%: calcium carbonate with grinding fineness of 3,000 cm2/g 97.0–97.5, sodium fluoride 0.5–0.7, composition containing, wt%: polyvinyl acetate polymer 85–90, dibutyl phthalate – not less than 5, water – up to 10, 2.0–2.3.
EFFECT: reduced water absorption, increased electric resistance and bending strength of foam concrete.
