Research Abstract	The present research reproduces the water behavior model in micropore by the result of water permeability test and molecular dynamics simulation. It is become clear that permeability of concrete and water viscosity in micropore are affected the difference of chemical composition or L-J potential of pore wall. Furthermore, constitutive low of viscosity in micropore is built by the result of this research.
