I am involved in the design of earthworks for diaphram retaining wall. It is suggested to fill the trench excavation with bentonite slurry to support it before concreting as bentonite slurry is lighter than concrte so will be replaced during pouring. However I came in contact with new concept of cation exchange capacity as a fundamental property to describe the clays, has anyone know what is it, how is measured and applied as far as bentonite is concerned?
