Time dependency and similarity of decay process of chloride diffusion in concrete under simulated marine tidal environment

According to the main climatic factors of natural tidal environment, nine concrete mixtures as same as that in site were designed and exposed in the simulated environment for up to 400 d. The effects of water-cement ratio, admixture and exposure time on chloride concentration and time-varying apparent and instantaneous chloride diffusion coefficient were investigated. Furthermore, the similarity between the time-varying chloride diffusion...
