The bentonite on the periphery absorbs water and swells outwards to fill the technological void (Fig. 13b), meanwhile, water migrates from the periphery to the dry center due to the suction gradient. This leads to a non-uniform distribution of degree of saturation and swell strain (ε 1 > ε 2), which in turn induces the build-up of tensile stress.
