ASPECTS OF WHITE CEMENT PRODUCTION

The results of research aimed at the development of chemical technology for the production of white cement under the conditions of resource conservation and energy saving according to the program of sustainable development are given. Based on computer calculations using the created programs Clinker and RomanCem the quantitative ratios of carbonate aluminum and silica-containing components of the raw material mixtures for the production of white Portland cement low-temperature firing cement (? 1200 °?) and Eco-cement were determined As a result of the study of 3-component systems based on chalk with aluminum hydroxide dust quartz aerosil and microtalc new compositions of starting mixtures were developed with a decrease in the content of carbonates and accordingly emissions of CO2 into the atmosphere with a minimization of the content of colored oxides and a corresponding increase in the whiteness of cement.
