GENERAL DESCRIPTION |
||
|
Hydrated lime, chemically known as calcium hydroxide, calcium hydrate or caustic lime, is produced by reacting water with high calcium quicklime in an atmospheric hydrator. It is a white powder form decomposes on heating producing calcium oxide.It is soluble in water and the solution is a medium strong base reacting violently with acids and attacking many metals in presence of water . Hydrated lime makes it suitable for a wide range of applications including: the treatment of potable water, waste water and municipal sludge, as a chemical process additive; the stabilization of toxic waste for site remesiation and various construction uses including soil stabilization and anti-stripping in asphalt mixes. |
