Abstract

To unveil the effect of powder particle size on the water retention characteristic (WRC) of compacted GMZ bentonite under a state of constant volume, powder particle size and shape distributions of two GMZ bentonites (GMZ01 and GMZ06) were investigated by employing the dynamic digital imaging technology and WRC tests related to these two bentonites were conducted with both osmotic and air phase methods used for suction control. It turns out that under a state of constant volume, the water content increases gradually with the decreasing suction, and the effect of powder particle size on the WRC seems quite faint within a high suction range but relatively obvious within a low suction range.
