However, the molecular structure of the different grinding agent is different, it leads to the different grinding aid grinding dispersion effect., And cement in different mineral compositions during grinding with different grinding mechanism, Such as C2S mineral need depolymerization, And mineral C3S need crack stress corrosion crack propagation. So in the process of cement grinding, using only a molecular structure of grinding aid can appear the function is not perfect, the effect of one sector. So you need to different molecular structure of grinding aid
