[V-550] Comparison of accelerated tests for judging salt pretentive properties of concrete using new materials
Keywords:salt damage, chloride-ion immobilization material, electrophoresis Test
Research on concrete materials is widely conducted, and is discussed in terms of chloride ion penetration depth and diffusion coefficient. At present, accelerated tests are performed in many studies. In this study, we aimed to understand the validity of these accelerated tests for new materials, and compared the results of accelerated tests of concrete using materials with different mechanisms of salt damage resistance. A chloride-ion immobilization material was used. In addition, the combination with an expanding material was also studied. As a result, the suitable test method differs depending on the mechanism of the salt barrier effect.
