A REVIEW OF METHODS TO DETERMINE THE MOISTURE CONDITIONS IN CONCRETE

A wide range of methods for the laboratory and in situ measurement of moisture conditions in concrete and related materials are reviewed in terms of their purpose, principles and practicalities. The effects of sampling volume, sample geometry, pore fluid composition and moisture gradients are considered. Methods based upon destructive sampling, relative humidity, resistivity, dielectric properties, thermal properties, infrared adsorption and neutron scattering are reviewed. Destructive sampling and relative humidity measurements can provide reliable data that is relevant to a wide range of concrete properties, including durability and permeation. Microwave and neutron scattering methods seem to warrant further development for moisture measurements in concrete. (TRRL)
