Based on the above,the authors discussed the relation between the montmorillonite content,the exchangeable cationic type between layer and its amount,the montmorillonite structure and the swelling performance of bentonite.

The data from the determination of cation exchange capacity and montmorillonite contents in expansive soils have been used in evaluation and classification of expansive soils according to occupation standard of TB 10042-95.

Clay mineral composition and smectite contents were measured using XRD and dye absorption methods.

It was shown by field investigation and lab tests that the types of altered rocks were mostly those of montmorillonitization,and the altered clay mineral was mainly pure montmorillanite,which rendered the altered rock both soft and expansive.
