    gypsum regulates the heat of hydration as also the ettringite formation for progressive chemistry. In the anxiety of not to retard cement if the gypsum is reduced below the threshold level heat of hydration is commensurately profuse leading to internal thermal stresses and incohesiveness. This is where the role of gypsum is evident as retarder.
