The application of the fire-retardant heat-insulating coatings the application of light fillers is considered the effective method of fire protection of structures. Work is dedicated to the development of the new effective cement fire-retardant and high-temperature (oxidation-resistant) vermikulitobetonnykh composites with the use of ashes and pumice. It is revealed, that the application of construction gypsum and lime as the agent of the concealed hydraulic activity of pumice it made it possible to considerably reduce the expenditure of cement without reduction in the strength of fire-retardant composite. By wood by that saponified 0,1- 0,3% of the mass of cement the expenditure of water for the mixture is reduced during the introduction of resin, the density of vermikulitobetona decreases by 40-50 kg/m3. Is investigated the influence of the parameters of fiber reinforcement by basaltic fibers on the properties of vermikulitobetona. Are revealed the high fire-retardant properties of the developed fibrovermikulitobetonnykh composites. It is established that the addition of the volcanic pumice of the fraction d< of 0,16 ppm 30% of the mass of cement significantly increases the high-temperature (oxidation-resistant) properties of concrete block with a simultaneous increase in the bending strength and without noticeable reduction in the compressive strength. The replacement of the part of the volcanic pumice by the distended vermiculite makes it possible to reduce the average density of the vermikulitobetonnogo composite and to increase their high-temperature (oxidation-resistant) properties.

"This article presents the results of research shrinkage of Portland cement with the addition of gypsum and alumina cement. A technique for the ultimate shear stress of cement paste on his spreadability on the glass and method of estimation of heterogeneity of the mixture was suggested. It is shown that the definition of the area blurring the mixture with a digital camera, followed by treatment with the results using a graphical editor allows to obtain more accurate data on the limit tension of the mixture and its homogeneity. It was found that binder comprising 78% of portland cement, 21,5% of gypsum and 0,5% of aluminous cement has low shrinkage for 3 days. The optimum dosage of additives gypsum and alumina cement depends on the chemical and mineralogical composition of portland cement. "

The results of research on the effectiveness of a multistage crushing of concrete scrap by the "soft" regime are given. It was found that the processing of concrete scrap by this technology can significantly improve some properties of recycled concrete aggregate, particularly crushability, water absorption, shape factor "average thickness of the grain" and porosity. The result of this treatment is the formation of a significant amount of particulate material. This material can be used as a fine filler in the technology of self-compacting concrete. It was found that self-compacting concrete based on products of crushing concrete scrap has a strength of 50 MPa after 28 days of curing in normal conditions, and more than 70 MPa after one year of storage in dry-air conditions. It was established that received concrete has a lower modulus of elasticity, which should be considered when choosing the fields of its application.

The development of new effective composites on the basis of technogenic raw material and local materials, which are characterized by low prime cost and improved physicomechanical characteristics, is urgent task. Deficiencies in gypsum in those binding and articles possibly as a result of the creation of composites with the use of effective fillers and dispersed reinforcement. Earlier we developed the gipsovermikulitobetonnye composites with the application of unslaked lime and withdrawals of the saw-milling of volcanic tuff. Use in the composites of pumice, basaltic fibers and portland cement will make it possible to enlarge raw-material base for obtaining the composites with the improved physicomechanical characteristics. The optimum relationship of the components of gypsum, ashes and portland cement, which would ensure obtaining composite with the improved physicomechanical properties with the smaller expenditure of binding agent is revealed.

Is proposed the stock mixture for preparing the gypsum concrete composite, which ensures the decrease of the specific expenditure of gypsum binding composite to 30,0% without reduction in the strength. The optimum relationship of components for preparing the gypsum concrete composite is revealed: the gypsum: ashes - 1:1, portland cement - 10 20% of the mass of gypsum. The influence of the parameters of fiber reinforcement is investigated by basaltic fibers on their properties with the application of a rotatable plan of the second order of the type of regular hexagon. It is revealed, that the maximum values of the parameters of optimization are observed in the central region of plan s i. Compression strength of the fibrogipsovermikulitobetonnogo composite increases 1,16-1,18, with the bend - 1,62-1,73 times with respect to the strength of initial matrix. The developed composites make it possible to reduce the expenditure of portland cement per 30% and to increase the coefficient of softening to 0,8. Further studies for the study of the fire-retardant properties of the developed composites.

Long-range building materials with possible complex of desired properties are silicate-natric adhesive-based composites. One of effective ways to increase silicate-natric composites water resistance is using of modifying compounds containing polyad metals ions (Zn2+,Ca2+,Mg2+,Al3+).

For analyzing XRD patterns date base PCPDFWIN, v. 2.02, 1999, (JCPDS) was used. It is clear that as a result of sodium silicate and ethanoate zinc water solutions interaction in optimal range zinc salt is fully under alkaline hydrolysis. It is also highly likely that this interaction produces supplementary compounding sodium acetate, at the initial stage, and various forms of zinc orthosilicate and hydrooxyde, characterized as insoluble and low-soluble compounds respectively, that promotes water resistance increasing of studied composites, when low-baked (110°С). In terms of researches compounds of various profiles are developed and recommended (heat-isolating, heat-isolating-constructive, constructive) with high functional and operating characteristics).

This article presents the results of comparative studies of the effectiveness of superplasticizers (SP) of different chemical nature in the flooring mixes. The mixes were prepared by using of blended binder based on Portland cement, alumina cement and gypsum. The effect of the type of superplasticizer and its dosage on the spreadability of the mixture, strength and shrinkage of building flooring mortar at different ages was investigated. It was found that all additives, with the exception of SP Sika Viscocrete 105P, characterized by rapid loss of fluidity of the mixture. The strength of the mortars does not depend on the type and dosage of additive at last age and strength decreases in mixes with additive of SP Melflux PP 100 F based on polyethylene glycol at early age. It was investigated the influence of the type and dosage of SP on the shrinkage of flooring mix on the basis of a blended binder. The received dependence is due to the relationship between the degree of dispergating of the cement suspension with different type of SP and shrinkage of binder stone.
