Abstract
This report presents a new proposal for conducting the water capillary absorption test of hemp concretes and establishing the parameters useful for analyzing the obtained results. Based on the standards of traditional materials such as concrete and mortar, a testing protocol was developed and executed by eight laboratories from RILEM TC 275-HDB through interlaboratory testing. Homogeneous cubic specimens of hemp concrete with an edge length of 150 mm were cast and distributed to the laboratories, where they were conditioned before undergoing test. By adopting the new testing procedure, consistent results were achieved after analyzing data in both square root of time and log-time regimes. For each regime, two pairs of parameters CA and k (square root of time regime), and IRA and K1 (log-time regime) were utilized to compare the data and successfully validate the interlaboratory testing.
