FIELD: chemistry. ^ SUBSTANCE: invention relates to compositions based on mineral binding materials, such as portland cement, and can be used in the industry of construction materials when making concrete, fibre concrete, cement-fibre construction materials, roofing slate, plaster, finishing coats and stucco moulding. The composition for producing construction materials contains cement, sand, water and carbon material. The carbon material used is an aqueous suspension of cavitational-activated carbon-containing material which contains multilayer carbon nanostructures with layer spacing of 0.34-0.36 nm and particle size 60-200 nm, polydispersed carbon tubular formations with dimensions of 10-6-10-5 m, hydrogenated carbon fractal structures with dimensions of 10-8-10-5 m and active loose carbon with graphite defective microcrystals with dimensions of about 10 . ^ EFFECT: high compression strength of construction materials. ^ 3 dwg,1 tbl |
