Abstract
A research project to develop standard test methods for measuring transport coefficients of concrete for gases, water and chloride ions is described. Since the moisture concentration in concrete is a most important parameter in affecting the transport parameters, a preconditioning method was developed to install a controlled water content with a homogeneous distribution in the test specimens. The effectiveness of preconditioning was evaluated in an initial intercomparison testing. The Cembureau setup was selected as a standard method for gas permeability measurements. For the capillary absorption of water, a modified ponding test was recommended.
