強化セメント硬化体を製造することを目的とする。[Detailed Description of the Invention] [Purpose] When manufacturing a fiber-reinforced hardened cement body using carbon fibers as reinforcing fibers, when cement, water, carbon fibers, etc. are mixed, the carbon fibers become entangled with each other, The purpose of the present invention is to produce a hardened fiber-reinforced cement body that prevents ball-like formation, has a smooth surface, and has high strength.
［背景技術］ セメント類の補強用繊維としては、アスベスト（１） 、ガラス繊維など種々のものが使用されている。[Background technology] Asbestos (1) is used as reinforcing fiber for cement. , glass fiber, and various other materials are used.

った。本発明はかかる事情に鑑みてなされた。Searches have been made for reinforcing fibers to replace these fibers. Under such circumstances, the present inventors have attempted to manufacture a fiber-reinforced cement hardened body using carbon fibers. However, in such a case, when the raw materials are mixed using standing water, the carbon fibers become entangled with each other and form a ball shape, making it impossible to mix uniformly. This phenomenon cannot be avoided even if a highly efficient mixing device is used.As mentioned above, when carbon fibers are shaped into a ball to produce a cured product, the surface of the cured product becomes The appearance becomes uneven, and the reinforcing effect is not sufficient. Therefore, this carbon fiber is used only when the mixture has a high water content, or when the amount of water mixed is small, the mixing time is shortened to prevent it from forming into a ball shape. However, although this method can prevent unevenness on the surface of the cured product, it is still not possible to achieve a sufficient reinforcing effect. The present invention was made in view of such circumstances.

が多い。The amount of water to be mixed cannot be strictly determined as it varies depending on the shaping method employed, but it is usually sufficient if it is 30 parts or more per 100 parts by weight of cement (hereinafter referred to as "parts"). If it is less than 30 parts, uniform mixing will not be possible and there will often be problems in shaping (3).
