AN OVERVIEW OF LIME SLAKING AGT Group

process of adding water to calcium oxide to produce calcium hydroxide is referred to as hydration process or lime slaking. The hydration of CaO, commercially referred to as quick lime, is an exothermic process releasing a great quantity of heat. This hydration process when done with just the right amount of water is called "Dry Hydration."
