FIBER FOR REINFORCING CONCRETE AND CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a fiber for reinforcing concrete which prevents lowering of a bonding force between the fiber and concrete by forming unevenness on the surface of a covering material itself, and to provide a concrete structure with which the fiber for reinforcement is mixed.SOLUTION: There is provided a fiber for reinforcing concrete which is formed of a core material 1 formed of an inorganic fiber that is resistant to ultraviolet rays, and a covering material 2 covering the core material 1 and formed of an organic resin that is resistant to alkaline, where unevenness 7 is formed on the surface of the covering material 2 itself.SELECTED DRAWING: Figure 1
【課題】被覆材自体の表面に凹凸を形成することによって、コンクリートとの結合力が低下することがないコンクリート補強用繊維、および、この補強用繊維が混入されたコンクリート構造物を提供する。【解決手段】紫外線に強い無機系繊維からなる芯材１と、芯材１を被覆する、アルカリ性に強い有機系樹脂からなる被覆材２とからなるコンクリート補強用繊維において、被覆材２自体の表面に凹凸７が形成されている。【選択図】図１
