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.…
