FIELD: industry of building materials. ^ SUBSTANCE: invention relates to compositions based on mineral binding agents. The composition for producing building materials based on the cement binding agent, water and carbon nanostructures comprises metal-containing carbon nanostructures consisting of a mixture of polyvinyl alcohol with copper (I) or copper (II) chloride chosen in the mole ratio = (1-20):1 that are heated up to temperature 300°C in taken in the following ratio of components in the composition, wt.-%: cement binding agent, 15-75; indicated metal-containing carbon nanostructures, 0.01-2.5, and water, the balance. The composition can comprise additionally from 2 to 10 wt.-% of organic binding agent or technological additives chosen in the ratio = (1-6):1 mas. p. p. to the cement binding agent content. Invention provides enhancing physical-mechanical indices, in particular, the compression strength value and reducing energy consumption and the material prepared cost. Invention can be used in industry of building materials in making block and monolith concrete, polymer-cement mortars, foam concrete, slate, stucco and finishing covers also. ^ EFFECT: improved and valuable technical properties of composition. ^ 3 cl, 2 tbl, 2 dwg, 6 ex |
