The basic compound of a kiln input are carbonate rocks: limestones and marls. The optimum content of CaCO 3 in the raw material for the clinker baking is 75-80%. In the case when the composition of the basic raw material differs from these values, various mineral additions are used,
Clinker: combinability of mixes - Understanding Cement
Clinker composition is evidently one of the key factors which determine cement quality. Composition is controlled mainly by suitable blending of raw materials, but there are limitations to what can be achieved. Before considering these limitations, a summary of the clinkering process, and of the role of the liquid phase, may be useful.Mineralization in Cement Clinker Process,16.07.2020· Enables the usage of raw materials with higher content of SO3.
