- Abstract
- As the concrete is the porous material, the water or air will permeate freely in concrete, therefore the durability of concrete
will be able to decrease. But the porous material is from surface with the rust inhibitor that it permeate the concrete internal to
be possible, to inflict a pressure and also it is possible to permeate the rust inhibitor until steel-frame location.
The objective of the study is to investigate the depth of penetration of concrete water forced in under pressure. For this
purpose, the experiments for the depth of penetration by selecting the factors and levels such as water pressure, water
pressurizing time were executed. The flow of water of concrete examined theoretically and experimentally. As a result, It is
found that in the case of low water pressure approximately 0.15MPa or less, the flow is Darcy seepage flow, the same as flow
in an ordinary sand stratum, whereas in the case of high water pressure, the flow is diffused seepage flow accompanied by
internal deformation of concrete. This study attempts to develop a method that penetrates corrosion inhibitors up to the location
of steel bars and investigate the penetration depth of corrosion inhibitors by verifying moisture migration in concrete under an
applied pressure.
