Ordinary Portland Cement: Uses, Advantages & Disadvantages

During the manufacturing of cement, silica undergoes a chemical reaction with calcium to form di-calcium and tri-calcium silicates which adds strength to the cement. The high amount of silica provides strength to the cement, but its setting time is delayed. Alumina: A large amount of alumina accelerates the setting but weakens the cement.
