Predicting moisture in field concrete - decisive parameters

Abstract

A review is made of the decisive parameters when predicting moisture conditions in a concrete structure exposed to natural climate. The required material properties such as the desorption isotherm, the scanning curves and the moisture transport coefficient are presented and discussed. The translation of parameters describing a natural climate into boundary conditions at a concrete surface is commented upon and examples are given on the effect of including or neglecting different parameters.
