This material will react with the moisture in the air, and as such, it can be used as a desiccant. In the presence of moisture, lime reacts slowly with carbon
The hydration of CaO, commercially referred to as quick lime, is an exothermic process releasing a great quantity of heat. This hydration process when done with just the right amount of water is called "Dry Hydration." In this case the hydrate material is a dry powder. If excess water is used for hydration, the process is called "Slaking."
This study investigates the water transfer mechanism of quicklime modified centrifugal dewatering clay. A small-scale centrifuge device was used to investigate the change of bound water content in modified clay under different laboratory test conditions including quicklime content and curing age, and analyze the water transfer mechanism …
