摘要
本文考察不同组份石膏对水泥强度的影响，发现用硬石膏取代二水石膏可提高水泥的强度。石膏组成中硬石膏含量越高，水泥的强度增长越快。硬石膏组份中混有少量碳酸钙。
The influence or gypsum with different components on cement strength is investigated in this paper and it is found that the cement strength can be inereased by replacing gypsum(CaSO4·2H2O )with anhydride. The more anhydride contents are in the gypsum components,the more quickly the cement strength grows. Small amount of calcium carbonate helps the growth of early cement strength
