Abstract
The presented scientific article deals with the actual problem of complex processing and disposal of industrial waste from metallurgical and chemical industries in order to obtain building materials, in particular to create heat-resistant building mixtures from them. Special attention is paid to the technological processes of manufacturing heat-resistant construction mixtures from overburden, enrichment tailings, slurries and slags. A critical analysis of the current state of the processing of these types of waste and the production of heat-resistant building mixtures from them is carried out. The article provides an overview of modern technologies and their practical examples in the field of creating environmentally friendly heat-resistant construction mixtures based on recycled materials. In addition, the results of an experimental study on the development of building mixtures for the production of heat-resistant building mixtures from industrial products of vanadium production are described. The industrial product of vanadium production was investigated by chemical and X-ray spectral analysis methods. The data obtained provides an overview of the material that can be used as a component of a mixture for the production of heat-resistant construction material, applicable in obtaining various types of construction mixtures and heat-resistant blocks. To obtain heat-resistant building mixes, cement M 400, liquid glass and chamotte were mixed in various proportions, and then dried at a temperature of 100℃ for 24 hours. Further, the dried materials were kept at 1000℃ for 10 hours, which, to assess heat resistance, were heated in the temperature range of 800-1800°C for 30 minutes, followed by abrupt cooling with water. The resulting building heat-resistant mixtures had high strength characteristics (compressive strength from 32 to 45 MPa) and good heat resistance/heat resistance.
