Abstract
The diffusion of water in concrete at temperatures between 50°C and 95°C has been considered in an earlier paper. The present work describes drying tests which have been made at 30°C and 70% relative humidity on concrete spheres of various diameters. These tests indicate that the usefulness of elementary diffusion theory is limited for these conditions since it was found that the diffusion coefficient was a function of the concentration of evaporable water. An extension of the model in which the diffusion coefficient is a function of time (and hence moisture content) has been investigated and an expression is proposed which gives satisfactory results.
