Slaking

Slaking is the process of alternate wetting and drying. Rocks, especially those containing clays, tend to swell on wetting, with subsequent contraction on drying. When water enters the pores of a rock, the rock dilates, creating tensile stresses and generating tension cracks (Yatsu, 1988).
