Influence of cementitious binder content on moisture transport in stabilised earth materials analysed using 1-dimensional sharp wet front theory

Experimental work was conducted to determine the influence of cementitious binder content on the moisture transport in partially-saturated stabilised earth materials. Data is presented for the influence of binder content on the initial rate of suction and the sorptivity. The partially-saturated sorption obeys the i/t0.5 linearity rule demonstrating dependence on the σ/η0.5 relationship. The transfer of moisture has been analysed and explained using 1-dimensional sharp wet front theory. The increased porosity, as a result of increasing binder content, gives significant increase in sorptivity.
