Slaking weathering
WebSep 1, 2024 · Slaking depends, to a large extent, on the volume of air inside the aggregates, the rate of wetting, and the shear strength of wet aggregates ( Le Bissonnais, 1996 ). To date, most previous studies about aggregate stability are focused on these material compositions, but seldom on soil porosity.
