ALKALI RESISTANT ORGANIC FIBER FOR CEMENT REINFORCEMENT
PROBLEM TO BE SOLVED: To provide an alkali resistant organic fiber for cement reinforcement excellent in adhesiveness with a cement matrix even in a cement molded body after primary curing where curing is not enough, capable of sufficiently exhibiting reinforcement curing during a manufacturing process such as form removal or transportation and capable of suppressing crack or breakage of the cement molded body.SOLUTION: There is provided an alkali resistant organic fiber having average fiber diameter of 3 μm to 900 μm and containing a cement curing accelerator inside, wherein the content of the cement curing accelerator is 0.1 mass% to 30 mass% based on mass of the alkali resistant organic fiber.SELECTED DRAWING: None
【課題】硬化が不十分な一次養生後のセメント成形体においてもセメントマトリックスとの接着性に優れ、脱型や移送等の製造工程中に補強硬化を十分発現させることができ、セメント成形体のひび割れや破壊を抑制することができるセメント補強用耐アルカリ性有機繊維を提供すること。【解決手段】３μｍ以上９００μｍ以下の平均繊維径を有し、内部にセメント硬化促進剤を含有する耐アルカリ性有機繊維であって、前記セメント硬化促進剤の含有量は、前記耐アルカリ性有機繊維の質量に対して０．１質量％以上３０質量％以下である、耐アルカリ性有機繊維。【選択図】なし
