Quicklime

Quick lime is processed white powder with chemical formula CaO. It is processed by the calcination process of Limestone. Limestone is a naturally occurring sedimentary rock consisting of mainly calcium carbonate, along with some other crystalline forms of Calcium. The calcination Lime Stone is carried out by crushing limestone and burning with coal powder. This calcination results evaporate of CO2 which makes quicklime (CaO). Now it is crushed into powder form of different required sizes. Quicklime can react with water at room temperature and makes Ca(OH)2.
The quicklime often ground into fine power by pulverize up to ideal for mixing with additives or other materials. Quicklime can also be hydrated with water (slaking) that results in Hydrated Lime Ca(OH)2.
