EFFECT OF LOAD BEARING MATERIALS ON SUSCEPTIBILITY TO BIOFILMS GROWTH

Popis výsledku v původním jazyce

Preventing a biofilms growth on exterior facades of buildings is one of the ways how to preserve the original buildings appearance and thus their proper aesthetical function. Since the biofilms growth is strongly conditioned by the hygric and thermal conditions on the surface, a proper hygrothermal performance and interactions between materials involved is essential. This paper studies an impact of load bearing material on surface conditions on a lime-cement plaster from the point of view of susceptibility to biofilms growth. An influence of autoclaved aerated concrete, solid brick and sandstone is studied when exposed to dynamic boundary conditions in form of reference climatic data. Being obtained using computational modeling of coupled heat and moisture transport, the results revealed a substantial influence in that respect. The best performance exhibited the autoclaved aerated concrete as the duration of convenient conditions for biofilms growth was lower by 40% when compared to solid brick and sandstone.
