Lime or calcium oxide is the most important ingredient of cement. The cement contains 60 to 67% of lime in it. It is obtained from limestone, chalk, shale etc. Adequate quantity of lime in cement is helpful to form the silicates and aluminates of calcium. If lime is added in excess quantity the cement becomes unsound as well as expansion and disintegration of cement will occur.
