HIGH-STRENGTH FIBER-REINFORCED MORTAR, HIGH-STRENGTH FIBER-REINFORCED HARDENED MORTAR, AND MANUFACTURING METHOD OF HIGH-STRENGTH FIBER-REINFORCED HARDENED MORTAR
PROBLEM TO BE SOLVED: To provide high-strength fiber-reinforced mortar by which a light-weight and high-strength fiber-reinforced hardened mortar having high strength can be manufactured while cost reduction is achieved.SOLUTION: Powder, which contains ordinary cement by 30 to 40 wt.%, pozzolanic fine powder by 10 to 15 wt.%, fine aggregate of grain diameter 0.1 to 1.0 mm by 45 to 55 wt.%, and chemical admixture by 0.55 to 0.65 wt.%, is allowed to contain water by 10 to 12% at a weight ratio to the powder and kneaded, and a curved fiber piece 2 which is formed in a curved shape by using metal fiber having a diameter of 0.15 to 0.3 mm and tensile strength of 2000 to 3500 N/mmis kneaded by 1.5 to 2.0% at a volume ratio to the powder. A length L1 of a straight line connecting both ends 3,3 of the curved fiber piece 2 is set to 10 to 20 mm, and a maximum depth L2 of the curved fiber piece with respect to the straight line is set to 0.5 to 1.5 mm.
【課題】軽量で高強度を有する高強度繊維補強モルタル硬化体をコスト低減を図って製造し得る、高強度繊維補強モルタルを提供する。【解決手段】普通セメントを３０〜４０重量％と、ポゾラン質微粉末を１０〜１５重量％と、粒径０．１〜１．０ｍｍの細骨材を４５〜５５重量％と、化学混和剤を０．５５〜０．６５重量％とを含む粉体に、水が該粉体に対する重量比で１０〜１２％含有されて練り混ぜられると共に、直径が０．１５〜０．３ｍｍで引張強度が２０００〜３５００Ｎ／ｍｍ2である金属繊維を用いて湾曲形成された湾曲繊維片２が、該粉体に対する体積比で１．５〜２．０％、練り混ぜられている。該湾曲繊維片２の両端３，３を結ぶ直線長さＬ１は１０〜２０ｍｍに設定されると共に、該直線に対する該湾曲繊維片の最大深さＬ２は０．５〜１．５ｍｍに設定されている。【選択図】図１
