Interaction of Portland cement minerals (alite, belite and alumina ferrite) with lime and sulfur mixing is investigated. It is established that during hydration of minerals the maintenance of SiO 2 in a liquid phase increases, hydration process is accelerated. Use of such mixing with concentration of sulfur to 180 g/l allows to increase the strength of cement materials on 20-40%.
