Hygric property estimation of porous building materials with multiscale pore structures

The hygric properties of porous building materials can be numerically estimated from pore structure information. These pore structures are captured by micro-CT scanning, resulting in a virtual network of pores and throats. Such pore network models of porous building materials are typically multiscale, as building materials commonly have wide pore size ranges. In these materials, the numerous fine pores play a significant role in determining the material’s hygric properties. This paper hence quantitatively studies the effect of these subsidiary pores by utilizing a multiscale pore network model.status: publishe
