Abstract
In HAM simulation, the wall structure was always simplified with homogenous material layers. However, in actual composition, the various brick bond types indicate different brick and mortar joints in massive brick construction, which affect moisture transportation and hygrothermal performance. In this study, numerical simulation were performed to evaluate the liquid movement through the interface of brick, mortar and air. Relative humidity and temperature at the interface are assessed with VTT mould and algae growth model as performance indicators in different cavity wall configurations. The severity of the moisture risk varied depending on the location and width of the airgap in the wall structure. The thinner brick outer leaf exhibits higher moisture content at the cavity interfaces, increasing the risk of moisture damage. The more material involved, the higher risk of moisture damage compared to homogenous material.
