Abstract
This paper describes a model for predicting the leaching degradation from the concrete in contact with water. The degradation mechanism was considered based on the degradation condition of the specimens obtained by electrochemical acceleration tests and diffusion tests, and the model was proposed. Analyzing the test results obtained from diffusion tests were carried out using mass transport equation. In the case of diffusion coefficient are 1E-12 [m2/sec] for non degraded region and 1.7E-10 [m2/sec] for degraded region, the computed result was close to the test result and showed the appropriateness of the model.
