This paper presents the application of discretised, electrical conductivity measurements as a relatively simple technique to monitor both the temporal and spatial moisture profiles of a range of mortar mixes, with and without supplementary cementitious materials. To this end, the mixes were conditioned under two curing regimes representing poor and good curing in a simulated hot-climate environment before being subjected to water absorption. A simple approach is presented to evaluate the volumetric water-content during absorption in terms of conductivity measurements. It is shown that when these profiles are presented in a Boltzmann format, they collapse onto a master-curve. The significance of adequate curing is highlighted.
