Abstract

Instead of natural gypsum with FGD gypsum as cement retarder, study the affection of different gypsum content on the properties of ordinary Portland cement. The results showed that gypsum can replace natural gypsum as cement retarder. There is larger surface area and setting time, and appropriate content in the gypsum can improve the compressive strength of cement.
