Abstract
It is significantly different in use of various admixtures on chloride ion penetration behavior of concrete. However, the mechanism is not understood. In this study, we conducted the non-steady state electrophoresis test by concrete using various admixtures, it was confirmed salt penetration performance. And the salt penetration mechanism was clarified by performing the determination of salt immobilization at each depth position by cement paste. Furthermore, in order to salt immersion test due to high salt concentrations used for accelerated test to determine whether the applicable available in various kind of cement such as using various admixtures.
