| 内容記述 | The purpose of this research is to predict penetration behavior of chloride ions in concrete under marine environment. Wherein, concrete structures such as wharves, jetties, docks, breakwaters, piers, dolphins, etc, are exposed to salinity of seawater. The complex marine environment is a jumble of perpetual submergence, intermittent cycling of wetting and drying spells by high and low tide ebbs, wave splashing/pounding, and 100% humid chloride impregnated atmosphere. Ingress of moisture, carrying chloride ions, is central to all these phases of marine environment, though with varying degrees of penetration by all the three transport processes- diffusion, convection, and quasi-adsorption. In this research real time marine environment phases are modeled in laboratory controlled conditions. And a series of experiments have been performed with different combinations of chloride concentrations (to represent seawater), temperature variations, and wetting/drying spell cycle durations. The chloride penetration profiles thus generated are compared with analytical chloride penetration profiles of DuCOM- a durability model developed by Concrete Laboratory, The University of Tokyo, Japan. | |||||||||
