Micro-mechanism of Shear Strength and Water Stability Enhancement of Montmorillonite by Microwave Heating

open access: yesMaterials Research, 2022
Microwave heating potentially reinforces the muddy intercalation to eliminate slope failure. Montmorillonite has the worst water resistance among the muddy intercalation components, which is a primary facet of inducing muddy intercalation failure.
