Use of Industrial By-products from Metallurgical Production for the Development of Heat-Resistant Building Mixes and their Molding in an Improved Device

In the context of the increasing volume of industrial waste and stricter environmental requirements, the urgent task is to efficiently process them to produce products with high added value. In this work, the composition of industrial products of vanadium production formed during the hydrometallurgical processing of rare metals is investigated, and the possibility of their use for the production of heat-resistant building mixes is substantiated. A comprehensive analysis, including X-ray, X-ray fluorescence, and scanning electron microscopic methods, revealed a high content of silica, aluminum oxides, and refractory minerals that determine the heat resistance of the material. Optimal compositions of building mixes based on Portland cement, liquid glass, and chamotte have been developed, providing compressive strength up to 45 MPa and resistance to thermal cycling at temperatures up to 1800 ° C. The design of a device for forming building blocks based on industrial waste from metallurgical production by vibration pressing is proposed, designed to ensure high density and geometric stability of products. The results obtained confirm the possibility of complex industrial waste disposal with the simultaneous creation of environmentally safe, durable, and heat-resistant building materials used in energy, metallurgy, the chemical industry, and civil engineering.
