... mass decreases its shear strength and increases deformability. Specific type of weathering when wetting and drying cycles are involved is termed "slaking". The slaking is characteristic for fine grained rock mass (mudstone, clay shale, marlstone, siltstone, claystone). Softening by means of slaking...
