A number of simple shear test have been performed on sandy clay and concretespecimens with and without bentonite mudcake at contact. The constitutive relations such asstress-displacement, dilative and the strength relations have been discussed in details. It wasfound that thin bentonite mudcake between sandy clay and concrete increases the shearstrength, the sliding between soil and concrete in addition to the vertical displacement. Thebentonite mudcake has a dual reaction; the upper face interacts with soil and the lower faceinteracts with concrete, showing different effects.
