GROUT MATERIAL ADDITION FIBER, GROUT MATERIAL INCLUDING THE SAME, AND MANUFACTURING METHOD OF GROUT MATERIAL
To provide a grout material addition fiber which has good dispersibility in a grout material, does not deteriorate flowability of a grout material, and has leakage suppression while having an irregular cross-sectional shape, a grout material including the same, and a manufacturing method of a grout material.SOLUTION: The invention relates to a grout material addition fiber including a polyolefin-based resin, wherein the grout material addition fiber has a fiber cross-sectional shape having three or more protrusions with a ratio Lt/Wt of a maximum width Wt of the protrusion and a length Lt of the protrusion of 0.5 or over and 3 or under. The invention also relates to a grout material addition fiber including a polyolefin-based resin, wherein the grout material addition fiber has a fiber cross-sectional shape of three or more protrusions, the protrusion having a portion tilted toward a center of the fiber, the maximum width Wt and a root portion width Wb satisfying Wt/Wb of over 1.0.SELECTED DRAWING: None
【課題】異形断面形状を有しながら、グラウト材における分散性が良好であり、グラウト材の流動性を損なわず、漏れ抑制性を有するグラウト材添加繊維、それを含むグラウト材、及びグラウト材の製造方法を提供する。【解決手段】本発明は、ポリオレフィン系樹脂を含むグラウト材添加繊維であって、前記グラウト材添加繊維は、繊維断面の形状が３つ以上の凸部を有し、凸部の最大幅Ｗｔと凸部の長さＬｔの比Ｌｔ／Ｗｔが０．５以上３以下である、グラウト材添加繊維に関する。本発明は、また、ポリオレフィン系樹脂を含むグラウト材添加繊維であって、前記グラウト材添加繊維は、繊維断面の形状が３つ以上の凸部を有し、前記凸部は、繊維の中心に向かってくびれた部分を有し、最大幅Ｗｔと根元部分の幅ＷｂのＷｔ／Ｗｂが１．０を超える、グラウト材添加繊維に関する。【選択図】なし
