Research Abstract

The purpose of this study is to determine the carbonation speed and the penetration speed of chloride ion of concrete with ground granulated blast-furnace slag (GGBFS) and to investigate the effects of carbonation and salt damage to the limit state of steel corrosion. Electron probe micro analysis (EPMA) was performed to obtain the detailed distribution of chloride ion. A sensor to monitoring steel corrosion was made on an experimental basis
Firstly, normal-strength and high-strength concrete with GGBFS were tested in laboratories. High replacement ratio, high fineness, and long wet curing increased resistance to carbonation and chloride ion penetration. Chloride ion penetration of high-strength concrete was restrained at surface layer, and carbonation depth and penetration depth of chloride ion hardly increased. Only the concrete with GGBFS could resist to an antifreezing agent such as calcium chloride. Moreover, GGBFS could delay combined deterioration of carbonation and chloride penetration, and of carbonation and acid rain.
Secondly, past researches on the limit state of steel corrosion and the results of exposure tests were summarized. It was found that the important factors to dominate corrosion were concentration of chloride ion, wind velocity, temperature, the deviation of temperature and humidity.
Then, a method using EPMA to obtain the detailed distribution of chloride ion in concrete was verified experimentally. The results by EPMA method well agreed with the results by usual titration method.
Lastly, practicality of the sensor made on experimental basis was examined. The condition that the steel wire of sensor corroded and electric resistance of it increased was clarified, and there is prospect of a practical application of the sensor for structures.
