Heat-resistant concrete of fine-grained structure attracts special attention of refractory applications manufacturers. The task of optimizing the grain size composition of heat-resistant concrete fillers on the basis of by-products and related products of silicon carbide (SiC) production and waste products of abrasive tools production on a ceramic bond of fine-grained structure is of research and practical interest. It is proposed to use grain size compositions of gapped grading for a fine-grained cement system of heat-resistant concrete. The analysis of methodological approaches in the calculation of the grain size composition of concrete fillers allowed us to determine the Fuller formula as an optimal one from a practical perspective. Due to the use of gapped grading of the grain component of the concrete composition, an optimal ratio between the size of the grains of quartz sand and the waste of abrasive production was achieved. Balanced distribution of the filler in concrete mix made it possible to obtain intimate contact between their grains, which resulted in dense, “well-packed” concrete structure, and will further enable 5-10% saving of the cement binder. The compressive strength of samples with gapped grading filler was 38.7 MPa, the thermal resistance (water, 800°C) amounted to 16 thermal cycles.

Possibilities of application of DIN EN 13036-4 Characteristics of road and airfield covering are considered. Test method. Part 4. Method of measurement of sliding resistance. Testing with a pendulum device to assess the coefficient of adhesion of road markings. This method is not applicable for diagnostics and more advanced scientific studies of rough and cohesive properties of road surfaces. The standard can be useful to control coupling properties of road markings, airfield pavements, examination of traffic accidents or for additional evaluate and evaluate the quality of road works, which, however, can be much better resolved based on domestic indicators standard deviation raznovysotnyh of Krasnoglinsky and raznolikosti geometry mikroheranhvatho road surface.

Creation of new efficient composite materials and the technologies of their manufacturing are inseparably coupled with corrosion protection of cement stone, which allows preserving construction products from fracture and ensuring their long service life. The development of new compositions of composite materials based on the industrial wastes from regional enterprises and aimed at the corrosion protection of construction products and structures is an urgent task for construction and technology professionals. A filled two-component polymer system (FTPS) for complex protection of construction materials and structures against moister and aggressive environments, which is based on secondary polymer and mineral raw materials, exhibits impregnating properties and can be used as a polymer additive to cement binding matter. The new mineral-polymer binder significantly changes the properties of the resulting material providing it with corrosion-resistance. The introduction of the FTPS polymer component in addition to the main mineral binder (cement) into the composition of concrete mix will allow changing the properties of concrete compositions through the modelling of their internal structure.
