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 ...
