โœฆ Synopsis


Portland clinkers containing side by side the phases C$, and &As, and optionally also C,AF and C,S, ay be produced by burning pertinent raw meals with added small amounts of CaF, to temperatures 1250-1300ยฐC. Such clinkers exhibit a significantly improved grindability as compared to ordinary portland cement clinker. The Sterength development of cements made from these clinkers depends greatly on the amount of added gypsum and at optimum gypsum additions is similar to that of ordinary portland cement.
