Role Of Gypsum In Cement Production

Gypsum and Cement Production two elementary building materials. Cement is used everywhere imaginable for example, as a binder for concrete, mortar or screed, making it one of the worlds most important building materials. If we just consider concrete, most of our infrastructure and architecture simply wouldnt be conceivable without it.
