composition of raw materials for cement

Responsible for quality and uniformity of the different cement types is most of all (next to the chemical composition of raw materials) the grain size distribution of cement which is a result of the component's grinding fineness If the cement's chemical composition doesn't vary only the grinding fineness determines the strength class The higher the grade of fineness the faster the
