中文摘要	A modification of the testing procedure was adopted to improve the PERMIT lots migration test method, a non-destructive method to evaluate the quality of concrete ill real structures. The steady state migration test procedure was reanalysed front the viewpoint of electrolysis The peak current obtained in the PERMIT ion migration test correlated well with the chloride diffusivity, the theoretical relationship between these was discussed and ail equation for calculating the effective chloride diffusivity in concrete from the peak current was determined the flew process Was found to be quicker and more effective than the typical process of the PERMIT loll migration test and to simplify the test procedure. As ail application example, the effect of different controlled permeability formworks for improving the resistance of cover concrete to the penetration of chloride toils was investigated using the modified PERMIT ion migration test.
