Chemicl parameters defining clinker composition

The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/(2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker. A clinker with a higher LSF will have a ...
