The exothermal effect upon interaction of calcium and silicon oxides
Annotation
Thermodynamic analysis is performed (TERRA software) of the lime-silica interaction for all possible lime-to-silica ratios at normal pressure. The components of the exothermal reactions are calculated. The adiabatic temperature of silica combustion in the lime is found. The heat of the chemical reaction is determined. The enthalpies of the initial rough material and the combustion materials are calculated. The evolution of the silica combusting in the lime, including formation of the stochiometric glass, wollastonite, rankinite, and pseudo-cement, is considered. The thermodynamic analysis is performed under the supposition of use of chemically pure substances with the absence of external heat and specific additions.
