Flint clay breaks with a pronounced conchoidal fracture and resists slaking in water. In 1924 a hydrator plant at Betchworth Limeworks was installed for slaking the lime. These include sub-processes of cryofracture, insolation weathering, slaking, salt weathering, bioturbation and anthropogenic impacts. Slaking is the process in which earth materials disintegrate and crumble when exposed to moisture. Sulfate arrests slaking, causes the cement to set quickly and stronger.
