Application of Ash-Slag Ceramics for Low-Rise Construction

The experience of involving ash-slag waste in the production of ceramic bricks (hereinafter ASW) is analyzed. An assessment of the production of ceramic bricks for 2020–2021 in the Russian Federation has been made. Using a complex of studies, it is established that alumino-silicate rocks – loams can be an alternative source of raw materials for the production of full-bodied ceramic bricks by semi-dry pressing with the addition of ash-slag waste in the amount of 28–35% and silica gel 11%. The results of research on the study of chemical, mineralogical and physico-mechanical properties of ash-slag ceramics based on 2 and 3 component compositions are presented. With the use of electron microscopic equipment, images of the microstructure of ceramic samples with 35% ASW, burned at a temperature of 1050^оС, were obtained.
