4 PRIMARY CEMENT COMPOUNDS & THEIR ROLES - …
Jul 14, 2017· The C 3 S that forms in a cement clinker contains about 3-4% of oxides other than CaO and SiO 2. Strictly speaking, this mineral should therefore be called alite rather than C 3 S. In a typical clinker the C 3 S would contain about 1 wt% each of MgO, Al 2 O 3, and Fe 2 O 3, along with much smaller amounts of Na 2 O, K 2 O, P 2 O 5, and SO 3 ...
Clinker Substitution - Cembureau
The use of other constituents in cement and the reduction of the clinker-to-cement ratio means lower emissions and lower energy use. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum). The current average clinker-to-cement ratio over all cement …
Lime Saturation Factor - an overview | ScienceDirect Topics
The cement clinker must be correctly burned, to minimise its free lime (CaO) content with the least expenditure of energy (Taylor, 1997). The free lime content of clinker is regarded as a practical measure of the degree of raw mix clinkerisation and is used as a means of controlling the quality of clinker …
