Abstract

 Liquid water in micro pore behaves peculiarly by wall friction. This study is aimed to build a model which takes into account the mech anism of fluid in micro pores for predicting the permeability in concrete. Yield stress model used frequently in fluid dynamics was applied to the flow of liquid water in concrete, and then the effect of kinetic and static friction on liquid water behavior from wall was expressed. Furthermore, viscosity model for liquid water in micro pore was proposed based on the result of experiments and then incorporated into thees timation scheme for liquid water flow through micro pores in concrete. The validity of these models was verified by comparing calculated data with experimental data of permeation test of saturated concrete.
