摘要

The paper proposes a combined application of composite theory and Powers' model for microstructural development for the estimation of the diffusion coefficient as a function of the moisture content of a defect-free cementitious material. Measurements of chloride diffusion in mortar samples (440 kg/m~3 rapid-hardening Portland cement, w/c =0.5, maturity minimum 6 months) stored at 65 percent and 85 percent RH, as well as in vacuum-saturated mortar samples, illustrate the applicability of the method.
