MASS TRANSFER OF WATER VAPOUR THROUGH CONCRETE

Serviceability of concrete is often related to strength, and the water/cement ratio upon which strength is closely dependent. The capacity of concrete to resist aggressive environments and to protect reinforcing steel depends on permeability, which is frequently related to water/cement ratio. This study shows that for constant initial porosity, permeability is not strongly dependent on water/cement ratio within the water/cement ratio range 0.42 -0.77 but is strongly dependent on initial porosity within the initial porosity range 0.14 -0.29.
