Grindability of portland cement clinker and the influencing factors

How to improve cement fineness economically and effectively is a problem concerned by cement enterprise. Two methods are widely used--improving the grinding technics and adding grinding aids. Started with clinker composition and structure, the grindability of Portland cement clinker is studied as well as the influencing factors in order to improve grindability of Portland cement clinker from the angel of clinker preparation technics. It is concluded that the aim of increasing Portland cement fineness can be reached economically through changing the composition of cement clinker and transforming manufacture technics.
