ABSTRACT

The present work is to introduce a new approach to measuring the effective permeability of building materials by using spontaneous water imbibition. A new linear relationship between water imbibition rate and the reciprocal of air recovery is derived and used as the basic theory to obtain the permeability information. The impact of buoyant-force change on the imbibition results is taken into consideration, which makes our results more accurate and reliable. The calculated effective permeabilities of three building materials, including limestone, concrete, and brick, are reasonably compared with permeability data in the literature.
