It is well known that most of property of concrete is influenced by its pore structure. ln particularly permeability of concrete is dependent on its pore structure. Therefore, it is beneficial to know durability of concrete that pore structure is measured exactly. We already developed the technique to make clear the pore structure in hardened cement paste by gallium intrusion and the following EPMA observation. In this research, using a image acauired by EPMA estimates diffusion coefficient with random walk which is many particles are walking in pore structure with random. The permeability of NaCl solution is measured by method of diffusion cell. Relationship between permeability of NaCI solution and pore structure by measuring gallium intruded method is discussed. As a result, pore connectivity and permeability is closely relationship.
