LIME SLAKING 101
In many of these applications, hydrated lime, or calcium hydroxide (Ca(OH) 2), is used. This is produced by adding water to quicklime (calcium oxide, CaO). Initially forming a dry hydrated lime product, the further addition of water creates a hydrated lime slurry in a process known as slaking—the focus of this white paper. Publication Date:

Hydration of high-calcium quicklime with methanol–water mixtures
It is then discharged into a cooler from which it is conveyed to a storage silo. According to Oates [3] the hydrated lime that is produced in this process, has high specific surface area and good handling properties, disperses well and is far more effective in the removal of acid gases compared to a normal hydrated lime.
Lime Treated Soil Construction Manual
What is 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.
What is Quicklime and How is it Made?
The term 'lime' is commonly used to denote all calcium-based inorganic substances. Actually, there are two types of lime – quicklime and slaked lime. The name 'quicklime' comes from the property of the substance to react vigorously or 'quickly' with water. Being highly caustic in nature, it is said to have a 'thirst' for water.
