Abstract

 Recently years, the surface penetrant as protection material has been adopted as one of the preventive measures of chloride induced deterioration of concrete structures. In this study, the concretes with two kinds of surface penetrants (silane type and silicate type) were investigated through the long-term exposure test. The properties of chloride ion penetration, the apparent diffusion coefficient of chloride ions and so on were evaluated using the different mixture proportion of concrete. This report is composed from the results of 5 years exposure test.
 The test results were summarized as follows: (1) Resisting the chloride ion penetration of surface penetrant was continued enough during 5 years exposure test, (2) The benefit of surface penetrant was cleared promising for the low-strength concrete.
