INFLUENCING OF PHOSPHATES ON SYNTHESIS AND PROPERTIES OF SULFOCLINKER CEMENTS

Abstract

Processing of phosphogypsum on sulfoaluminate-silicate cement allows to receive decorative and usual rapid-setting cements of mark 400-600. In comparison with white Portland cement it allows to save a significant amount of technological fuel. Productivity of the furnace raises on 15-25% for the account of lower contents of limestone in a raw mix of sulfoaluminate-silicate cement in comparison with Portland cement a raw mixture. We have investigated the behaviour of phosphorus in this process.
