FIELD: chemistry.
SUBSTANCE: invention pertains to production of foamed concrete. The crude mixture for making foamed concrete contains the following components with the given percentage mass ratios: 18.0-20.0; flue ash from a thermal power station with specific surface of 2800-5000 cm2/g 36-40; air-entraining extraction colophonic resin 0.11-0.17; carboxylmethyl cellulose 0.05-0.07; superplasticiser C-3 0.4-0.8; sodium methylsiliconate 0.02-0.04; asbestos-cement wastes, burnt at 700-1000°C and then ground up with specific area of 4000-5000 cm2/g, 18.0-20.0; water constitutes the remaining percentage.
EFFECT: reduction of cement consumption and recycling of asbestos-cement wastes.
