Abstract
The technological properties of heat-resistant concrete on a liquid-glass binder are presented. Self-disintergrating ferrochrome slags are used as a hardener, which can sharply increase the weather and heat-resistance of such concrete. In addition, due to the use of a retarder for the setting of a liquid-glass binder, the speed of construction of monolithic structures increases with their required construction quality. Modified heat-resistant concrete with improved technological characteristics was obtained on liquid glass with the addition of K-setting retarder, fireclay filler and hardener – ferrochrome slag, which made it possible to carry out high-quality laying of the concrete mixture into a densely reinforced cone-gas separator structure without reducing the required strength and fire-resistant characteristics of concrete.
