Effect of Chloride Type on Penetration of Chloride Ions in Concrete徐港摘 要:<正>The influence of chloride type on the diffusivity of chloride ions in concrete was studied by experiment. The result shows that the glectric resistance of concrete and the chloride diffusion coefficient are influenced by chloride type. For the same water/cement ratio (W/C......
