Economic and practical feasibility of using ash and slag mixture and phosphoric slag in the production of ceramic bricks based on bentonite clay

One of the large-scale international environmental barriers is the increased pollution of ecological systems by aggressive waste, therefore, maintaining the environment in an appropriate form is a cornerstone not only for all mankind, but also for the planet as a whole. In addition, one of the most pronounced obstacles to the production process and the expansion of the range of ceramic products in the 21st century is the exhaustion of natural resources: clay raw materials, thinning ingredients, fluxes, additives that create porosity, etc. The rotation of natural raw materials to large-scale waste will significantly reduce the cost of bricks. Studies have shown that it is utopian to produce ceramic bricks without the introduction of preservatives in bentonite clay compositions. The composition, which includes 35 % phosphorous slag and 15 % ash and slag mixture, is identified as optimal for the production of bricks of the M125 brand.
