Lime has strong water absorption, and reacts with water to become calcium hydroxide (Ca(OH)2), commonly known as slaked lime or slaked lime. It has little solubility in aqueous solution, but it can further ionize calcium ions (Ca2+) and hydroxide ions (OH-) in aqueous solution, making the solution more alkaline.

Lime is produced through calcination or "burning." Limestone is subjected to a great heat -- 1,650 to 2,000 degrees Fahrenheit -- in order to drive off carbon dioxide, leaving pure lime. This process occurs in kilns: vertical shafts full of limestone with heat added through fireboxes on the sides.

The Lime-Saturation Factor. This factor has been used for kiln-feed control for many years in Europe and only recently has also found acceptance by American cement manufacturers. When the lime-saturation factor approaches unity, the clinker is difficult to burn and often shows excessively high free-lime contents.
