The invention relates to compositions of raw mixtures based on cement, used for the production of heat-insulating building materials, characterized by high fire-resistance.

Currently a proliferation of raw mix for the production of thermal insulation materials (building blocks), including in addition of Portland cement expanded polystyrene, or expanded clay, or slag.

The closest in technical essence to the achieved result of the proposed mixture and selected as a prototype is a peat-polymer mixture for making wall blocks comprising a base in the form of peat, and binder (see patent RU 2393128, publ. 20.07.2009).

However, the raw material mixture of the prototype has significant drawbacks. Such a mixture has a heterogeneous structure due to the heterogeneous composition of the coarse aggregate, which leads to inhomogeneity of the material, increasing the number of defects in the structure and, as consequence, to reduction of operational and technical characteristics.

The technical result is the obtaining of high fire-resistant and strength characteristics at constant density, lower thermal conductivity, improving the uniformity of the structure and the durability of thermal insulation material.

The technical result is achieved �eat that peat-polymer mixture for making wall blocks comprising a base 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 collection gas cleaning air industrial enterprises of dry polyvinyl acetate in the amount of 6% by weight of peat and dust - 2%) - 25, Portland cement CEM II-42,5 - 35, ammonium chloride - 10, DAP - 10 and water 20.

The experiments were carried out on the example of cyclone dust gas purification JSC "Nevyansky cementnik, containing in its composition, wt.%: SiO2- 12-13, Al2O3to 3, Fe2O3to 3, Cao - 40-45.

The types of peat in the composition tortolero mixture can be virtually any as individually, and mixtures thereof. But the most effective type of peat to achieve the specified technical result is a lowland peat because of its high density and resistance to fire.

Peat-polymer mixture for making wall blocks includes a base in the form of peat, and binder. The mixture consists of the following components, wt.%: peat, nanomodified suspension of polyvinyl acetate and cyclone dust collection gas cleaning air industrial enterprises of dry polyvinyl acetate in the amount of 6% by weight of peat and dust - 2%) - 25, binder e�ement is a Portland cement CEM II-42,5 - 35, ammonium chloride - 10, DAP - 10 and water 20.

Nanomodification peat the polyvinyl acetate and cyclone dust gas purification of air and industrial businesses are required to create high-strength structure material and increasing the strength of the border zone of adhesion of peat and cement. Making corporaton possible almost anywhere in the country because of the wide distribution of natural peat.

Nanomodification peat before mixing with cement and water in mixing devices and enforcement actions. Directly cooking tortolero mixture can occur in the same units. A freshly prepared mixture shape the future of thermal insulation building materials: blocks, slabs, etc.

The proposed invention was developed on behalf of the EMERCOM of Russia with the purpose of increasing the fire resistance of building constructions 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.

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