Regression analysis for determination of durability parameter values ofn marine concrete

摘要

The importance of determination of marine concrete durability and lifetime prediction parameters through regression analysis of exposure test results or field measurements is discussed. The parameters considered include the apparent diffusion coefficient, the apparent surface chloride content and the time attenuation coefficient of the apparent diffusion coefficient. According to the analytical expression of Fick's second law, the essential features and the procedure of regression analysis (curv
