INFLUENCE OF ORGANIC SHORT FIBER AND GROUND GRANULATED BLAST FURNACE SLAG ON FROST DAMAGE RESISTANCE OF CONCRETE

有機短繊維と高炉スラグ微粉末がコンクリートの耐凍害性に及ぼす影響

The purpose of this study is to clarify the influence of organic short fiber and ground granulated blast furnace slag on frost damage resistance. Freezing 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.有機短繊維と高炉スラグ微粉末がコンクリートの耐凍害性に及ぼす影響を明らかにすることを目的として、有機短繊維と高炉スラグ微粉末をそれぞれ単独および併用したコンクリート供試体を作製し、その凍結融解抵抗性について実験的検討を行った。その結果、淡水による凍結融解作用下では、繊維混入率および高炉スラグ微粉末の有無がコンクリートの耐凍害性に及ぼす影響は小さく、極めて良好な耐凍害性を示した。一方、海水による作用下では、高炉スラグ微粉末を混入することで耐久性指数が大きくなる傾向を示した。また、有機短繊維と高炉スラグ微粉末を併用した場合にはスケーリングが抑制される傾向を示すことがわかった。
