Slaked lime is the result of the slaking process of lime by adding water to quicklime ( calcium oxide ), leading to a chemical reaction and the formation of calcium hydroxide. This process typically generates heat and forms a pasty mass, which is used in various fields. Slaked lime finds wide application in construction as a binding material for preparing construction mixtures, plaster, putty, and other building compounds. This binding substance chemically interacts with carbon dioxide from the air, undergoing the slaking process to eventually revert to the state of calcium carbonate - a solid mineral substance that lends strength and durability to materials.
