The need to improve the technical level of production of construction materials, their product range, to improve product quality and reduce its cost requires the expansion of the raw material base, the use of resource and energy saving technology and design solutions. To implement all these it is necessary to conduct a more detailed study of the properties of ceramic materials and to investigate the behavior-modifying components of their formulations. This paper presents the development of the composition of ceramic mass for the production of bricks, a modified silicon-waste production of ferrosilicon.
