Stabilisation of α′ dicalcium silicate in calcium sulfoaluminate clinker
Calcium sulfoaluminate cements are widely used as special cements and, because of their low specific carbon dioxide emissions relative to those of Portland cement, they have potential for use in general construction. However, their widespread application has been limited by the relatively high cost of aluminous raw materials. As part of a broad programme on the optimisation of these cements, the clinker mineralogy was reformulated to enhance the activity and strength contribution of the silicate...
