What are the Roles of Gypsum in Cement Production

What are the Roles of Gypsum in Cement Production Gypsum can be used as a raw material, mineralizer, retarder and activator in cement plants. Among the components, SO 2 is used to balance the sulfur-alkali ratio in the calcining of clinker and improve the calcining operation and the service life of refractory materials.

Role of Gypsum in Cement and its Effects The Constructor

Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water. The process involved in hydration of cement is that, when the water is added into cement, it starts reacting with the C3A and hardens.

Improvement of Performances of the Gypsum-Cement Fiber

The novelty of this paper lies in the identification of the scientific patterns of the influence of thermal power plant waste (TPPW) on the hydration mechanism and the structure of the gypsum-cement binder (GCB). The classification of raw materials for the production of GCB has been developed taking into account the genesis, which contributes to the prediction of the properties of composites.
