要旨 Both of the ingression of chloride (Cl-) ions along the movement of NaCl solution due to capillary suction and diffusion through crack were studied. Cracked reinforced concrete specimens were exposed to NaCl solutions and penetrated profiles were tested by Electron Probe Microanalyser (EPMA). Diffusion coefficients (Dap) from crack surface of partially dry samples showed higher than those of exposed surface whereas saturated samples showed almost same from both surfaces. Dap were found to be time dependency as decreasing with time mainly due to continuation of hydration and other mechanisms. An empirical formula was proposed to estimate the notational surface Cl- ions concentrations (Cs).
