Cement-Clinker-Strength-Prediction-Model

2021-1-19 · Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by cement manufacturers when raw materials are found to be ...

What is the purpose of adding gypsum in cement?

Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the...

2021-2-1 · The PCC compositions did prepare with a variation of the addition of 0 - 5% gypsum where the clinker ratio did fix at 75%, and two other additives, namely limestone, and trass did add with a fixed ratio of 1.2: 1. The effect of adding gypsum to clinker measured by performing a mortar compressive strength test and the binding time at the ages of ...

The influence of gypsum ratio on the mechanical …

2011-3-1 · The strength of Compositions 1 and 2 rises in relation to the increasing quantity of gypsum GR in the binder.. The difference in mechanical performances of Compositions 1 and 2 is related to the amount of slag consumed: as the dose of gypsum GR in the binder is increased, so the slag activation and the mechanical performance also increase. Whereas high temperature …

Effect of Gypsum on Hydration and Hardening Properties …

2019-9-25 · The crushed clinker and the gypsum were ground to prepare cement by a planetary ball mill (Changsha Tencan Powder Technology Co. Ltd., Changsha, China) according to the mix ratio in Table 3. The cement was tested according to GB/T 8074-2008 Testing method for specific surface of cement—Blaine method and specific surface area was controlled at ...
