Development of Concrete Compositions Based on Alumochromite Cements

Abstract

The intensification of industrial thermal processes in various branches of science and technology requires the creation of new structural materials that, in addition to exposure to high temperatures, can withstand the aggressive effects of melts, electrolyte solutions, and high pressure. Refractory materials that currently exist are mostly piece products and require additional seam fastening, which significantly reduces the service life. Replacing artificial refractories with a monolithic seamless concrete lining allows you to meet all the necessary requirements for the operational reliability of a thermal unit1. The main directions in the development of technological solutions for the production of refractory unshaped materials is the selection of the optimal qualitative and material composition of the filler, which ensures the formation of the necessary physical, mechanical and technical characteristics of the working layer of the lining when heated to the operating temperature2 .
