Abstract
Sensitive clays are part of the collapsible soils. The origin of sensitivity has been investigated for many years. Some new facets of the development of microstructure in fine-grained soils are presented in the light of work on recent sediments and from projects looking at lime stabilisation of muds and sensitive clays. Particular attention is given to the response of to the microstructure to stress changes with the introduction of the porosity index (In) and to the development of cementation as a major source of bonding strength. Finally, cementation and leaching are presented as the processes leading to greater collapsibility in sensitive clays.
