Cement Particle Size Analysis - Sympatec

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 development of …
