Abstract
Chloride attack of concrete structure is a primary factor to deteriorate concrete structures durability. For this reason, recently many researches of chloride ion penetration and diffusion have been conducted. But it is difficult that verification of accuracy of predicted durability of RC structures because chloride ion diffusion coefficient is diversity according to equivalent age, composition, environment. In this research, it can be produced a accuracy of durability life prediction through reliability assessment and propose a prediction method of chloride ion diffusion coefficient of concrete applied assessment program of reliability. By way of this, we make test materials using different admixture and calculate chloride ion diffusion coefficient by RCPT test at each equivalent age. On the basis of this result, we indicate reliability prediction formula through reliability analysis for durability life design using Montecarlo method. And we verify propriety through comparing and analyzing of this proposed formula with investigation data of chloride ion diffusion studied the inside and outside of the country.
