Abstract: The measurement of the moisture content in concrete is an important issue for several applications in the construction industry. Calibration procedures are needed for qualifying quantitative methods, especially for indirect methods. A procedure for preparing concrete samples with well characterized and homogeneously distributed moisture contents has been proposed in order to provide the needed calibration samples. The methodology basically consists of a drying step from the water-saturated state, to the target moisture content. This is followed-up by a homogenization step, and an optional measurement of the quasi-equilibrium relative humidity. This last step allows defining the conditions for keeping unaltered the moisture state during subsequent work. The validity of the procedure is being checked in the framework of a round-robin test of RILEM TC 248-MMB, by using several techniques for measuring the moisture content and for checking the homogeneity of the moisture distribution within the samples.
