    The low-grade cement mainly used for masonry mortar is made from active mixtures, Portland cement clinker and gypsum. (15) Oil Well Cement. Portland cement clinker, gypsum and mixtures made of suitable minerals are suitable for cementing oil and gas wells at a certain well temperature. (16) Gypsum Slag Cement. The granulated blast furnace slag.Gypsum plays a very important role in controlling the rate of hardening of the cement. The retardation mechanism of gypsum is when cement is hydrated, gypsum reacts with C3A quickly to generate calcium sulfoaluminate hydrate which deposits and forms a protection film on the cement particles to hinder the hydration of C3A and delay the setting.

  • The Role Of Gypsum In Cement

    Feb 01, 2020 Generally Gypsum having purity than 80 as CaSO4.2H2O is considered suitable for mentaining SO3. If Gypsum having very Low purity can cause high innsoluble residue in cement and decrease the strenght due to high caly content. However high purity of gypsum ~88.0 is ideal.But u should count C3A in cement before deciding SO3 target.Find your perfect match.
