A particular brand of Portland cement is made using limestone, kaolinite and sand. Thethree raw materials are pre-calcined at 950°C, which drives off any carbon dioxide andwater chemically associated with the minerals. The bulk oxide composition of thecalcined materials is as follows: a) Assuming that the free-lime content of the clinker is zero, and bearing in mindthat gypsum has not yet been added, what proportions of the four main cementcompounds are potentially present?
