Hygric, thermal and durability properties of autoclaved aerated concrete

Popis výsledku v původním jazyce

The hygric and thermal properties of autoclaved aerated concrete (AAC) given in the manufacturers? lists include mostly just the thermal conductivity in dry state and generic data for the specific heat capacity and water vapor diffusion resistance factor. Durability characteristics are not listed at all. This greatly limits any service life assessment studies of AAC-based building envelope systems. In this paper, complete sets of hygric and thermal properties of three commercially produced AAC with different bulk density and compressive strength are measured, together with the basic physical characteristics and durability properties. Experimental results show that the thermal conductivity can be as much as six times higher in capillary water saturationstate than in dry conditions. Thermal conductivity is also found to increase up to 50% when temperature is increased from 2 C to 40 C. The dependence of moisture diffusivity on moisture content is remarkable; the differences as high as o
