Influence of gypsum fineness in the first hours of

2018-9-30  Influence of gypsum fineness on cement particle size distribution. The particle size distributions of the gypsum and clinker phases are shown in Fig. 2. The clinker has a granulometric distribution similar to that of the coarse gypsum. The medium and fine gypsum have larger particle size distributions (0.2–100 μm).
