수압을 받는 콘크리트에서의 수분 이동에 관한 실험적 연구

Abstract

본 연구에서는 고압을 받는 내압법에 의한 콘크리트의 침투실험을 통해 액체의 평균 침투 깊이를 산정하고, 평균 침투 깊이를 통해 압력과 시간에 따른 확산 계수를 실험적으로 검토하였다.

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, pressure 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 presue, the flow is diffused seepage flow accompanied by internal deformation of concrete.
