HYDRATION STUDY OF PORTLAND CEMENT MINERALS IN LIMY-SULFUR TEMPERE

The interaction of minerals of the Portland cement (alit, belit, alyumoferrite) was studied with a limy-sulfur tempere. Higher SiO2 content in a liquid phase was established at hydration as well as hydration process acceleration. The strength of cement materials could be increased by 20-40% at application of such tempere with sulfur concentration of 180 g/l.

Key words: Portland cement, clinker minerals, alit, belit, alumina ferrite, redox potential, me-chanical strength
