Development of binders from secondary raw materials of coal enrichment and their use in restoring and erecting construction objects

Abstract

EN: The process of coal enrichment is accompanied by the formation and accumulation of coal enrichment waste in significant volumes, which has a significant negative impact on the environmental condition of their storage sites. This occurs due to the large areas they occupy and the risk of contamination of even larger areas due to possible infiltration into the soil and subsequent contamination of groundwater. There is a problem of developing a technology for using such waste, for example, in the resource-intensive industry of production of clinker-free binders in order to reduce energy costs, emissions during production and further use of materials based on such binders in the restoration and construction.
