8 Main Cement Ingredients & Their Functions

2021-10-31  The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below: Lime: Lime is calcium oxide or calcium hydroxide. The presence of lime in a sufficient quantity is required to form silicates and aluminates of calcium. Deficiency in lime reduces the strength of property to the cement.
