The definition of the durable life of high performance concrete(HPC) structures resisting chloride ion penetration in marine environment has been proposed in the paper on the basis of the analysis of the life cycle of HPC structures Factors affecting the durable life of concrete structures are analyzed on the basis of Fick's Second Law Electro chemical methods used at home and abroad to measure chloride ion penetration are briefly described in the paper and the relationship between electric flux and diffusion coefficient is analyzed
