Towards The Problem Of Repurposing Industrial Wastes For Development Of Public Infrastructure

The use of polymetallic ore enrichment waste in the production of building materials improves the environment and increases resource conservation.These technologies include the production of composite cements based on industrial waste, used as active components of the binder.In the course of scientific research, the conceptual foundations of high-tech production of multicomponent composite cements based on hydraulic binders were developed.These cements have reduced cost and excellent construction and technical characteristics.Modern analytical methods were used to study the processes of structure formation in composite cements containing polymetallic ore enrichment waste.The mineralogical and chemical composition of these materials was established using X-ray phase analysis, microscopy and differential thermal analysis.The research results showed that the content of carbonates in waste from the enrichment of polymetallic ores, not exceeding 30%, does not have a negative effect on the strength of the samples.This opens up new opportunities for using these wastes as a component of composite cements, which not only reduces production costs, but also increases the environmental friendliness of the process.
