Abstract
This chapter contains results of research on the use of industrial waste in the composition of the starting mixtures for the manufacture of cement in accordance with modern resource saving requirements. In the experimental work, the methods of physico-chemical analysis of silicates and standardized testing of the properties of mineral binding materials were comprehensively applied. The object of the study was raw material mixtures for the production of low-temperature fired cement (≤1200 °C) based on the system carbonate rock (limestone) – multi-ton industrial waste (rice husk and TPP fly ash). Calculations and analysis of probable compositions of raw mixtures with the possible content of investigated industrial waste as man-made raw materials were performed using the "RomanCement" and "Clinker" computer programs. New compositions of starting raw material mixtures with content agro-industry and thermal energy waste were determined. The peculiarities of the formation of the phase composition and properties of the mineral binder during firing with the specified maximum temperature and varying the quantitative ratio of the components in the composition of the initial mixture are shown. A conclusion was made about the possibility of effective utilization of the investigated multiton industrial waste as man-made raw materials for the production of mineral binders for a comprehensive solution to the issues of resource saving and chemical technology for the production of silicate building materials.
