Lime • Lime is one of the basic building material used mainly as lime mortar in construction. • Properties of building lime, advantages, and uses in construction is discussed. • The broad category of lime is non-hydraulic and hydraulic lime. • The non-hydraulic lime is called as quick lime, fat lime or white lime or as lump lime. • Hydraulic lime sets under water and nonhydraulic lime do not set under water.
• Quick Lime is a form of lime is manufactured by the burning of stone that has calcium carbonate within it. • The burning temperature varies, say 900 degree Celsius and above for several hours. This process is called as calcination. • The solid product that remain after the removal of carbon dioxide in the calcium carbonate is called as the quicklime.
