Raw Materials of Cement - Expert Civil
High content magnesia makes the cement unsound. Calcium Sulphate ( CaSO4): This ingredients is in the form og gypsum and its function is to increase the initial setting time of cement. Sulphur (S): A very small amount of sulphur is useful in making the sound of cement. If it in excess, it causes the cement to become unsound.
