| Summary: | 碩士 === 雲林科技大學 === 營建工程系碩士班 === 98 === Based on Fick’s diffusion law, diffusion of chloride through concrete is analyzed. Experiment was conducted to obtain the data of quantity of chloride through sliced concrete specimen versus diffusion duration under different environmental conditions.Neumann’s modification for advancing model is applied to analyze the data to obtain the diffusivity and Neumann’s constant, which are critical to evaluation of diffusion rate and speed of the diffusion material in the medium.The result is to be used in qualifying chloride content in RC structure for evaluating the service life of a RC structure considering corrosion of steel reinforcing bar induced by chloride.
