Factory Tests of Ceramic Brick Technology with a Matrix Structure Based on Aggregated Ash Complexes

The relevance of using man-made mineral waste in the technology of ceramic wall products is shown. A promising direction for the production of ceramic bricks based on aggregated ash complexes is considered. A method of obtaining them is given, which ensures a decrease in the average density and an increase in the thermal characteristics of wall products. A brief description of the raw materials used in conducting factory tests is given, including thermal power plant fly ash, natural clay raw materials and a technological binder based on polyvinyl alcohol. The composition and technique of preparation of a granular press mass consisting of aggregated ash complexes are given. The parameters of pressing raw bricks and firing products in the factory are presented. Mechanical tests of compressive and bending strength of ceramic bricks based on aggregated ash complexes in a factory laboratory are shown. The results of a study of the physico-mechanical properties of an experimental batch of ceramic bricks with a matrix structure based on aggregated ash complexes are presented. A technological scheme for the production of ceramic bricks based on ash granules has been developed. The main stages of the full cycle of ceramic products production are given. A technological regulation has been developed for the design of the production of ceramic bricks from loam and ash-entrainment of thermal power plants.
