The invention relates to compositions of raw mixtures, cement based, used in the production of insulating building materials, characterized by an increased resistance.

Now spread the raw material mixture for the production of thermal insulation materials (building blocks), including in addition to Portland cement expandable polystyrene, or expanded clay, or slag.

The closest in technical essence to the achieved result of the proposed mixture and is selected as the prototype is peat-polymer mixture for the manufacture of fire resistant building blocks, including the basis in the form of peat and the connecting element (see patent RU 2393128, publ. 20.07.2009).

However, the raw material mixture prototype has significant drawbacks. Such a mixture has a heterogeneous structure due to the heterogeneous composition of coarse aggregate, which leads to heterogeneity of the properties of the material, increasing the number of defects in the structure and, consequently, to lower operational and technical characteristics.

The technical result is to obtain high fire resistance and strength characteristics at constant density, lower thermal conductivity, increase the homogeneity of the structure and durability of insulating material.

Delivered technical Reza�the adds is achieved by in tortolero mixture for the production of fire resistant building blocks, including the basis in the form of peat (mainly lowland) and the connecting element consists of the following components, wt. %: peat, nanomodified suspension of polyvinyl acetate and cyclone dust scrubbing air venture for the production of Portland cement (rate of dry polyvinyl acetate in an amount of 4% by weight of peat and dust -2%), and 25%, Portland cement CEM II-42,5 - 35%, sodium bicarbonate is 7.5%, calcium chloride and 7.5%, DAP - 5% water - 20%. The experiments were carried out on the example of cyclone dust scrubbing JSC "Nevyansk cementnik, containing in its composition, mass. %: SiO2- 12-13, Al2O3- 3, Fe2O3- up to 3, Cao - 40-45%.

Types of peat consisting tortolero mixture can be almost any, separately, and their mixtures. But the most effective type of peat to achieve the said technical result is a lowland peat due to its high density and resistance to fire.

Nanomodification the peat polyvinyl acetate and cyclone dust scrubbing the air of industrial enterprises are required to create high-strength structure material and increase the strength of the border zone of adhesion of peat and cement stone. Making corporaton possible almost anywhere in the country�s because of the wide distribution of natural peat.

Nanomodification peat must occur before mixing with cement and water in a mixing installations enforcement action. Directly cooking tortolero mixture can occur in the same units. Freshly prepared mixture is formed future heat-insulating building materials: blocks, slabs, etc.

The proposed invention is designed in the interests of EMERCOM of Russia with the aim of increasing the fire resistance of building construction in areas of high concentrations of people and is aimed at reducing fire risk peat insulating concretes due to alloying of peat nanoparticles, preventing interaction of carbon compounds peat with oxygen.

The addition of sodium bicarbonate enhances the fire resistance of the resulting building structures due to its insulating and inhibitory functions.

Calcium chloride accelerates the cement hydration, resulting in reduced initial and final setting time and shrinkage, at the same time, increasing its forward resistance, surface wear and resistance to cold weather. The use of calcium chloride increases productivity in the manufacture of building structures in 2.5-3 times by reducing the time of hardening of cement and improve the quality of manufacturing,�increasing production. The addition of calcium chloride helps to ensure building structures with sufficiently high strength and resistance to frost.

Building structures, which include diammonium phosphate, which have high flame retardancy.

Peat-polymer mixture for the manufacture of fire resistant building blocks, including the basis in the form of peat, and binder, characterized in that it consists of the following components, wt. %: peat, nanomodified suspension of polyvinyl acetate and cyclone dust scrubbing the air of industrial enterprises for the production of Portland cement (rate of dry polyvinyl acetate in an amount of 4% by weight of peat and dust - 2%), and 25%, Portland cement CEM II-42,5 - 35%, sodium bicarbonate is 7.5%, calcium chloride and 7.5%, DAP - 5% water - 20%.
