主　　题：durability effective diffusion coefficient steady-state migration test 

摘      要：To investigate the influence of initial curing conditions and exposure environments on chloride ions’migration in concrete,the specimens that were cured in different conditions and placed in several marine environments were *** amount of chloride ions passing through the specimen’s section was monitored in the accelerated chloride migration *** effective chloride diffusion coefficients(De)were calculated from the steadystate on the basis of Nernst-Planck’s *** results indicated that the initial curing conditions and the wet-dry interval of external environments have coupling influence on effective diffusion coefficient of chloride ion *** reflected the density and pore connectivity of *** co-effects of the initial curing condition and following exposure environment should be taken into account in durability design for concrete structure located in marine environment.
