ABSTRACT

The ability of porous building materials to absorb and transport water has several consequences related to building physics. Conventional concrete simulation models often neglect some fundamental aspects of multiphase flow in porous media. Infiltration of water from the upper surface to the lower surface of the concrete member is a key process that is often neglected. In this study, we present a theory of infiltration through a porous media that is made of concrete in a one-dimensional space. Based on this theory, it is established that the rate of imbibition in a concrete mold is influenced by gravity, capillarity, and absolute permeability. The study showed that concrete with low permeability is more durable compared to one with higher permeability.
