Ecological Systems and Devices Annotation << Back Environmental, Economical, and Practical Relevance of Recycling of Combustible Shale and Phosphoric Slag in the Production of Wall Bricks Without Using Traditional Natural Raw Materials Ivaev M.I., Safronov E.G., Brazhnikov M.A., Abdrakhimov V.Z. Industrial waste appears during the production of any products that are stored in landfills ("tailings dumps, "sludge storage", etc.) and negatively affects the environment and ecology in general. One of the global environmental problems of global importance is the problem of pollution of the natural environment with man–made raw materials, therefore, the preservation of the environment in its proper form is becoming a basic value both for all mankind and for planet Earth as a whole. Ceramic bricks, as revealed by the analysis, it is futile to produce the lowest grade M100 without using cleaners. Experimentally, it was found that in the ceramic composition, the growth of solvents: phosphoric slag and ash and slag mixture up to 25 % and an identical decrease in shale clay up to 75 % reacts to an increase in technical indicators. The subsequent increase in the quantitative content of pollutants and an adequate decrease in clay leads to a decrease in indicators. For the purchase of M125 grade wall bricks, a rational composition containing 18 % phosphorous slag and 7 % ash and slag mixture is used. Keywords: phosphoric slag, ash-slag mixture, interstitial clay, ceramic brick. DOI: 10.25791/esip.9.2025.1544 Pp. 36-44.
