Role of Gypsum in Cement and its Effects The Constructor
When is Gypsum added in the cement ? In the manufacture process of cement, clinkers are formed These cement clinkers are cooled down and added with small amount of gypsum The mixture then sent to final grinding process For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 25%The strength of cement is directly proportional to its fineness Because, smaller the particle of cement, it offers a larger surface area and larger surface area gives more heat of hydration, larger area for bond hence faster the development of strength However, the excess fine cement increases the cost of grinding and need more water inField vs Laboratory Testing of Cement GharPedia
