The invention relates to the construction materials industry, and in particular to compositions for the production of non-autoclaved aerated concrete, and can be used in the manufacture of products for construction purposes and in monolithic construction. Famous raw mix for the production of aerated concrete containing Portland cement, lime, aluminum powder, calcium chloride and water (RU patent No. 1491857, CL SW 38/02. publ. 1989). The disadvantage of this mixture is the complexity of the regulation of the process of structure formation crystallohydrate compounds due to the absence of plasticizer, which affects the physico-mechanical properties of cellular concrete. Known dry mix for the production of aerated concrete containing cement or cement and filler, water, and a pore-forming mixture comprising a plasticizer contains the specified dry pore-forming mixture composition, wt.%: cement 70, the aluminum powder pigment 12, powder water-soluble aluminum 12, cold-resistant plasticizer 2, water 4, number 0,3125 a 1.25% by weight of cement (RU patent No. 2253637, CL SW 38/02). The disadvantage of this mixture is the absence of substances which would stabilise the porous structure at the stage of curing aerated concrete, which would increase the porosity of the material. The objective of the invention is to increase plastic PR is knosti and the increase in volume of concrete while reducing the density of the material due to the regulation of pattern formation. This object is achieved in that the composition for the production of cellular concrete contains cement or cement and filler, water and dry pore-forming mixture comprising a plasticizer and a blowing agent. Dry pore-forming mixture further comprises carbon nanostructures, caustic soda and lime and/or slaked lime and/or lime, chlorine, and/or chalk, in the following ratio, wt.%: carbon nanostructures - 0,7; caustic soda - 3,3; plasticizer - 6,6; gasifier - 24; unslaked lime and/or slaked lime and/or lime, chlorine, and/or chalk 65,4. Dry pore-forming mixture is 0.35 to 1.5% by weight of cement. The proposed mixture for the production of cellular concrete provides the increase in non-autoclaved aerated concrete natural setting while reducing material density, and proliferation of plastic strength and regulation of pattern formation in the process of hardening of the material. Ground chalk introduced into the composition comes into physico-chemical interaction with lime hydrolysis elite and the companies in the cement and lime, is additionally introduced, forming with it an additional number of high-strength slightly basic of calcium hydro, strengthening structure of cement stone and porous concrete the whole. Introduction to the mixture an additional amount of lime and/or chalk is made from the calculation of the maximum binding of aluminate and allmaterial calcium cement ettringite and its stabilization in time. To prevent the collapse of ettringite at an early stage of hardening of non-autoclaved aerated concrete ambient temperature should not be above 60°C. the Resulting ettringite causes expansion of emerging cement, shrinkage compensating. As the filler used sand for construction works, which increased the weight and strength of non-autoclaved aerated concrete. As the plasticizer used Superplasticizer C-3, which can further reduce the amount of mixing water without reducing the mobility of the mixture, which gives a significant increase in the strength of non-autoclaved aerated concrete and improvement of all its other properties. The introduction of blowing agent in the structure of the composition creates a hollow area in the form of bubbles with air, carbon metal-containing nanostructures serve as a scaffold for the formation of crystalline hydrates of the cement, i.e. strengthen the walls of hollow areas. The walls of the bubbles become stronger and shrinkage, and increase the insulating properties. To obtain dry pore-forming socioconsult the following materials: filler sand for construction work according to GOST 8736-93; the blowing agent is aluminum powder brands PAP-1 and PAP-2 - according to GOST 5494; quicklime calcium - according to GOST 9179; the slaked lime calcium - according to GOST 9179; lime chlorine - according to GOST 19433; chalk ground - according to GOST 17498; plasticizer - superplasticizer C-3 on THE other 6-14-625; caustic soda - according to GOST 2263; carbon nanostructures. Production of carbon nanostructures have been synthesized from hydrocarbon condensed materials (aromatic hydrocarbons or polymers containing functional group), low-energy method of carbonization in the gel matrix (Patent RU №2221744 from 2002.04.08). For the production of non-autoclaved aerated concrete using dry pore-forming mixture, cement, water and a filler such as sand. As the binder is Portland cement brands HRC 400, 500 D0-20. Changing the ratio of components and volaterrae condition, you can widely change the density of the resulting cellular concrete: when the density of 400-600 kg/m3- thermal insulation; when the density of 600-900 kg/m3- structural thermal insulation; when the density 900-1600 kg/m3- construction. The specified dry pore-forming mixture is added to the solution in amounts of from 0.35 to 1.5% by weight of cement. A mixture of DL is the production of aerated concrete is prepared by mixing the components in the following sequence: water, filler, cement, dry pore-forming mixture, in the following ratio, wt.%: carbon nanostructures - 0,7; caustic soda - 3,3; plasticizer - 6,6; the gasifier 24; unslaked lime and/or slaked lime and/or lime, chlorine, and/or chalk 65,4. Volaterrae ratio in the raw material mixture is 0.5 to 0.8, with an average density of cellular concrete 400...1600 kg/m3; the temperature of the mixing water 20±5°C. the Time of mixing the components of the mixture 15-25 min before the introduction of the dry pore-forming mixture and 1...2 min - with a pore-forming mixture after its introduction. After the expansion of the molded product or the monoliths harden under natural conditions. Comparative data on known and proposed raw mixtures for the production of aerated concrete and its properties are given in the table.
Thus, it is seen that the application of the composition can increase the amount of steam formation in comparison with the known composition, therefore, improve sound and thermal insulation properties of the material. A significant advantage of non-autoclaved aerated concrete manufactured from the composition, is the reduced energy and the intensity of its production due to the complete elimination of traditional (apogrebnoi) heat-moisture treatment (autoclave, steaming, heating up, exposure and other species). Separate cooking dry pore-forming mixture provides along with the specific composition of the mixture of simplicity and availability of manufacturing foam ball the East concrete and allows to extend the term of its production and use in construction. We offer dry pore-forming mixture for the manufacture of construction products made of non-autoclaved aerated concrete allows to increase the strength up to the level of the best examples of aerated concrete domestic and foreign production; to reduce the average density, to minimize and even eliminate moisture and carbonizing shrinkage and significantly improve the performance properties due to the sharp reduction in capillary porosity. The mixture for the production of aerated concrete containing cement or cement and filler, water and dry pore-forming mixture comprising a plasticizer, a blowing agent, characterized in that the pore-forming mixture further comprises carbon nanostructures, caustic soda and lime and/or slaked lime and/or lime, chlorine, and/or chalk in the following ratio, wt.%:
