Abstract

This work is aimed at using the technogenic raw materials of the Kovdorsky GOK for the production of refractory materials. Currently, many researchers are engaged in the development of technologies for unshaped materials. The most demanded among them are refractory concrete. They are able to set and harden at low temperatures with the formation of structures that retain their characteristics when heated. In our work, concretes were obtained from a briquette based on forsterite concentrate obtained from the waste of the Kovdorsky GOK. Magnesium phosphate cement was used as a binder. As a result of the research, the grain composition of the charge was selected, the ratio of filler and binder to improve the structural properties of concrete was found, the effects of the composition and the temperature of heat treatment of concretes on the physical and technical properties were shown. Concretes have the following characteristics: bulk density 2170-2260 kg / m3, strength up to 50 MPa (at 25°C), volume change after heat treatment at 450-1000°C 1-2%. Recovering the waste of the Kovdorsky GOK by manufacture of concrete will lead to a qualitatively new use of non-renewable natural resources, reduce the rate of depletion of mineral raw materials in the subsoil, eliminate sources of environmental pollution and restore land occupied by waste.
