The results show that: PCE-type GA is effective in cement grinding. With 0.03% PCE-type GA added into cement clinker, the Blain surface area reaches to the highest at every ten minutes, and the volume percent of cement particles with size of (0–32 µm) reaches the highest. Excessive amount of PCE-type GA seems to impair the
