Abstract

The possibility of using 3-component charges in the production of wall ceramics by semi-dry pressing from aluminosilicate loams in a composition with ash and slag waste from CHP plants, cullet and silica gel obtained by the sol-gel method is considered. The physicochemical processes and phase formations occurring in the production of ceramic materials using WCO at the firing stage have been studied. It was found that the introduction of fluxes in the form of cullet and silica gel reduces the temperature of heat treatment and are intensifiers of mineral neoplasms that increase mechanical strength compared with samples made from 2-component compositions «loam + ASW».
