BUNDLED FIBER FOR ADDING HYDRAULIC HARDENED BODY, PREMIX CEMENT COMPOSITION AND HYDRAULIC HARDENED BODY CONTAINING THE SAME, AND METHOD FOR PRODUCING THE SAME
To provide: a bundled fiber for adding a hydraulic hardened body, which has improved bundleability when subjected to dry blending with the hydraulic material and is excellent in dispersibility in a slurry; a premix cement composition and the hydraulic hardened body containing the same; and a method for producing the same.SOLUTION: This invention relates to a bundled fiber for adding a hydraulic hardened body, in which a plurality of single fibers are bundled with a sizing agent, wherein: 1.0 mass% or more of the sizing agent based on a fiber mass is adhered to the bundled fiber; and the sizing agent contains a sulfosuccinate salt. This invention further relates to a premix cement composition and the hydraulic hardened body, which contain the bundled fiber for adding the hydraulic hardened body. This invention also relates to a method for producing the bundled fiber for adding the hydraulic hardened body, including steps of: imparting a treating liquid of the sizing agent, containing the sulfosuccinate salt, to a tow in which a plurality of single fibers are bundled; and bundling the plurality of single fibers by drying the tow to adjust the amount of sizing agent adhered to be 1.0 mass% or more based on the fiber mass.SELECTED DRAWING: None
【課題】水硬性材料と乾式混合した際の集束性が向上し、スラリー中の分散性が良好である水硬性硬化体添加用集束繊維、それを含むプレミックスセメント組成物及び水硬性硬化体、並びにその製造方法を提供する。【解決手段】本発明は、複数本の単繊維が集束剤で集束された集束繊維であって、集束繊維には、繊維質量に対して１．０質量％以上の集束剤が付着されており、集束剤はスルホサクシネート塩を含む水硬性硬化体添加用集束繊維に関する。本発明は、また、セメント、及び水硬性硬化体添加用集束繊維を含むプレミックスセメント組成物及び水硬性硬化体に関する。本発明は、また、単繊維が複数本束ねられたトウに、スルホサクシネート塩を含む集束剤の処理液を付与する工程、トウを乾燥して、集束剤の付着量が繊維質量に対して１．０質量％以上になるように調整して複数本の単繊維を集束させる工程を含む、水硬性硬化体添加用集束繊維の製造方法に関する。【選択図】なし
