Since slaking by definition involves the degrada­ tion of geologic materials, it follows that the properties of these materials play an integral part in the slaking phenomenon. These properties can be broadly characterized as stratigraphic or structural. Two stratigraphic components related to dura­ bility of a given material are lithology and min

Slaking - an overview | ScienceDirect Topics

If a soil has high quantities of Na + and the EC is low, soil permeability, hydraulic conductivity, and the infiltration rate are decreased due to swelling and dispersion of clays and slaking of aggregates (Shainberg, 1990). Infiltration rate can be defined as "the volume flux of water flowing into the soil profile per unit of surface area" (Shainberg, 1990). Typically, soil infiltration rates are initially high, if the soil is
