What is Quicklime and How is it Made?
Quicklime is a caustic compound known by its chemical name calcium oxide (CaO). It appears as a white powder when cold, and yellow when heated. Quicklime is produced by heating naturally-occurring limestone rock, which contains calcium carbonate. Being highly alkaline in nature, quicklime tends to react with the acidic carbon dioxide present in ...

Lime Treated Soil Construction Manual | Lime …
Lime in the form of quicklime (calcium oxide – CaO), hydrated lime (calcium hydroxide – Ca[OH]2), or lime slurry 1 can be used to treat soils. Quicklime is manufactured by chemically transforming calcium carbonate (limestone – CaCO3) into calcium oxide. Hydrated lime is created when quicklime chemically reacts with water.
