| Abstract |
A few problems about life prediction method, property evaluation method, exposure test of repair materials and finishing materials which is relatively easily deteriorated under the severe natural environment were discussed. The chloride ion diffusion FEM analysis taking due account of the property degradation of repair materials was carried out to emphasize the need for deteriorative properties evaluation with age and using them as input data of life prediction analysis. One of the conclusions is that it is important to know the deterioration pattern in consideration of outer causes like a circumstance and inner causes like a material's problem on deciding the serviceable life and suitable repair time. |
