To utilize the waste, accumulated in Ukraine, and optimize the clinker grinding process, chemical additive, which is a product of processing the polymer fraction of solid domestic waste was developed. The polymer fraction was used to obtain nitrogen-containing organic compounds, which have a significant influence on the clinker grinding process and physico-mechanical properties of cements and products based on them in the composition of additive.
It was found that additive effectively influences clinker grinding processes within the concentrations of 0,045-0,065 wt % and has almost no impact on the process of grinding active mineral additives. The additive in a broader concentration range (0,025-0,085 wt %) increases the strength of composite cements in all hardening periods and accelerates the setting time.
Additive, obtained by chemical processing of polymer fraction of solid domestic waste can be used in the construction industry as clinker grinding activator and cement strength increasing additive. Thus, it is possible to reduce the energy consumption in grinding technology operation and improve the physico-mechanical properties of composite cements, which in turn reduces the content of the cement component in such cements.
