Chemicl parameters defining clinker composition Understanding Cement

Chemicl parameters defining clinker composition Understanding Cement

Applied to clinker, it is calculated as: LSF=CaO/ ( 2 + 2 O 3 + 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 higher proportion of alite to belite than will a clinker with a low LSF.

Cement kiln Wikipedia

Cement kiln Wikipedia

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill); heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill).
