Construction composites based on man-made mineral fillers

At the same time there is no systematic approach to processes of producing facing materials on the base of natural and industrial waste materials that would rely on setting the criteria for forming the structure, forecasting and directed adjusting of ceramic material composition and process flow sheets of their production. The work contains the results of study on improving the grain distribution of high-silica technogenic products for obtaining facing ceramic materials with forecastable operating properties. The study presents a model of facing composite material on the base of quartz grain fill. The optimal grain distribution of high-silica wastes was detected with the purpose of adjusting the packing density of ceramic materials at the stage of feed preparation, moulding and baking.
