The effects of moisture content on Surface Water Absorption Test (SWAT) and on Torrent air permeability test were investigated. Three mix proportions of concrete and three kinds of curing conditions were provided. Water absorption resistance p600 and air permeability kT showed almost constant values when moisture content was lower than a kind of threshold value . The threshold values in moisture content measured by two moisture meters were exhibited respectively both for water absorption and air permeability.
