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.
