gypsum in cement industry

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 “setting of cement”.

Oct 31, 2019· In this process, the gaseous SOx is absorbed in limestone slurry and forms syntheticgypsum(SG) which can be a substitute for mineralgypsumbycement industry. FGD Gypsums of thermal power plants can become a major source ofgypsumfor the Indiancement industry. It can become a substitute for importedgypsumconsumption byindustry.

In cement industry, natural gypsum (CaSO 4 ·2H 2 O) is the most effective raw material for this purpose. In the naturalgypsumsources, anhydritegypsumcan often be encountered, so its effect oncement'squality parameters must be focused on [1-3].

GypsumandCementProduction - two elementary building materials. Cement is used everywhere imaginable: for example, as a binder for concrete, mortar or screed, making it one of the world's most important building materials. If we just consider concrete, most of our infrastructure and architecture simply wouldn't be conceivable without it. And gypsum plays a similarly important role inside buildings.

Depending on the tricalcium aluminate andgypsumcontent of ordinary portlandcement,the maximum ettringite content of the hydrated product at early ages is approximately 15%;cementingsystems containingindustrialby-products, such as fly ash, with lime andgypsummay have a higher ettringite content of, for instance, 20% (Solem and McCarthy, 1992); expansivecementsbased on calcium …

Mar 21, 2018· Gypsum is used as a retarding agent to control the setting time of cement. It gets added whilst clinker is ground into cement. Roughly speaking, cement production requires about 5% of gypsum. So a 1Mt/yrcementplant would require around 50,000t/yr ofgypsum.The crucial question for cement producers in West Africa is where is this gypsum coming from.
