Abstract

While many heat, air and moisture (HAM) transport models have recently been developed, a state-of-the-art review shows that their application is limited by lack of the reliable material data. Towards this end, an alternative approach to material characterization, called an Engineering Model of material characteristics is examined in this thesis. Series of moisture transport experiments were carried out on two building materials: aerated autoclaved concrete (AAC) and Portland cement plaster (exterior stucco). The experiments were to measure material characteristics, and to provide benchmark for the HAM model calculation. Furthermore, a ruggedness study was conducted on the factors that may have influence on the water absorption coefficient test. This thesis introduces the concept of a platform with a minimum number of measured points for the input to heat, air and moisture transport models. This thesis also presents results of parametric study conducted on the wetting and drying behavior of AAC, with respect to parameter variations and their interaction effects, including such parameters as capillary saturation, capillary liquid conductivity, water absorption coefficient, and moisture storage factor.
