    Aug 01, 2008 That indicated limestone could prolong setting time of PC clinker. Too less limestone content like sample a resulted in rapid initial setting. In case of limestone and gypsum coexisting like samples f, g and h, the setting time of cement could be normal when substitution of limestone for gypsum less than or equal 50.

    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.

    Effects of Gypsum on Cement. Gypsum prevents Flash Setting of cement during manufacturing. It retards the setting time of cement. Allows a longer working time for mixing, transporting and placing. When water is mixed to cement Aluminates and sulfates get react and evolve some heat but gypsum acts as coolant and brings down the heat of hydration. Gypsum cements possess considerably greater strength and hardness when compared to non gypsum cement.

    Cement - Cement - History of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.

  • Difference Between Lime and Cement What Is Lime

    Difference Between Lime and Cement What Is Lime

    Lime vs Cement. Lime hardens much more slowly than cement-containing mortars, making it much more workable. Lime is also less brittle and less prone to cracking, and any cracked areas can absorb carbon dioxide and mend over time. The cement hardens very quickly, but may be too strong for some applications, e.g., working with old bricks.
