Abstract

Moisture permeabilities (δv,) of mature concrete and cement paste with water-cement ratio (wo/C) 0.4, 0.5 and 0.6 have been determined as functions of the relative humidity (RH). These δv, can be used to calculate δv, of the aggregates including the interfacial transition zone (ITZ). δv, of granite has been preliminarily determined as a function of RH.
