Abstract
A method for determining the unsaturated hydraulic diffusivity of porous building materials using pin-type resistance sensor array was discussed. The transient moisture profiles and associated master curves were obtained using a 20 channel real-time automatic computer monitoring system. The cuboid samples of gypsum, plaster of paris and multifinish plaster with predetermined water/plaster ratio and effective porosity were analyzed by embedding 20 pairs of pin-type stainless steel electrodes along them. The moisture profiles were obtained by scanning the resistances across electrode-pairs. The results indicates the dependence of diffusivity on moisture content.
