| Research Abstract |
The purpose of this study is to clarified the influence of organic short fiber and ground granulated blast furnace slag on frost damage resistance. Fleezing and thawing tests of concrete by using organic short fiber and ground granulated blast furnace slag were examined. In the case of fresh water, the influences of fiber content and ground granulated blast furnace slag on frost damage resistance of concrete appear relatively small. Within the range of replacement ratio used in this study, the frost damage resistance was remarkably high. On the other hand, the durability factor of concrete increases with the replacement of ground granulated blast furnace slag in the case of sea water, and the scaling of concrete decreases by using organic fiber in combination with ground granulated blast furnace slag. However, the scaling increases remarkably in the case of large replacement ratio of fiber.
