The Experimental Method Comparison of Concrete Penetration
For comparing the difference between Salt ponding test and ASTMC1202 test, the same batch of specimens divided into two groups are tested, and the chloride ion diffusion coefficient was calculated with the corresponding theory. The results indicate that the concentration gradient is larger, the concentration decreased faster and the slope of figure is more steep in salt ponding test, and the chloride ion diffusion is deeper for the role of the electric field in ASTM test. Although the diffusion mechanism is different in two kinds of test, there is little difference between the two groups of test diffusion coefficient.
