ANALYTICAL STUDY ON HOMOGENIZATION OF PERMEABILITY IN CONCRETE AS A NONHOMOGENEOUS MATERIAL

Abstract

The analytical study on the development of the homogenization of permeability in concrete, which is composed of crack and uncracked region, was performed. The applicability of the proposed model was estimated due to the comparison with the leakage water experiments. Further, the homogenized permeability in concrete having the complex crack pattern was also estimated analytically. In the proposed model, concrete is composed of crack and uncracked region and then the discontinuity of hydraulic gradient on cracks are taken into account in micro-level.
