Relationship between surface air permeability and moisture behavior between surface air permeability and moisture

Research output: Contribution to journalArticlepeer-review

Abstract

The air permeability of the surface layer of concrete made from ordinary Portland cement, Portland blast furnace cement type B, and fly ash cement cast indoors and outdoors, was measured by the Wenner method and ceramic sensors. The effects of the water content in concrete at 1 year after casting on surface-layer air permeability were examined to evaluate the durability of newly built structures with surface-layer air permeability. The results indicate that the water content of concrete affects air permeability, but that it may be possible to conduct outdoor evaluations similar to those performed in a stable indoor environment by gauging the environmental conditions of a structure appropriately and adding Wenner method resistivity.
