Clinker: combinability of mixes - Understanding Cement

On a coal-fired works, the composition of the coal ash also needs to be allowed for, since the ash falls onto the part-reacted feed and combines with it. In practice, a works may have 5 or 6 raw materials in order to control composition. Alite is the clinker mineral that contributes most to strength in concrete, especially earlier strengths.

2015-1-6 · Clinkers are clumps of fused ash from burning coal and the reason they are called clinkers is because that is the noise they make when they rattle between the shaker grates of a coal stove. Well, as long as the shaker grates continue to shake, before they jam with the clinker that is stuck between them.

Clinkerization - Cement Plant Optimization

When coal is used as fuel, the ash content and its composition should be considered in raw mix design. LSF of clinker lies in the range of 92-98. Higher LSF at controlled free lime content translates to better quality of clinker (high C3S), difficult clinkerization, high heat consumption.
