Summary:PROBLEM TO BE SOLVED: To provide a fiber-reinforced cementitious composition capable of developing a desired flexural strength.SOLUTION: The cementitious composition is obtained by mixing a fiber reinforcement material to a cementitious matrix containing a binding material involving at least a cementitious hardenable material, water, and an aggregate, wherein the fiber reinforcement material comprises steel fibers having fiber diameters of 0.6 mm or less and fiber lengths of 25 mm or more and 40 mm or less and mixed at a rate of 200,000 or more and 4,000,000 or less per 1 mof the cementitious matrix.SELECTED DRAWING: Figure 1 【課題】所望の曲げ強度を発現させることの可能な、繊維補強セメント系組成物を提供する。【解決手段】少なくともセメント系硬化材を含む結合材と水と骨材とが含有されたセメント系マトリックスに、繊維補強材を混入するセメント系組成物であって、前記繊維補強材が、繊維径０．６ｍｍ以下であり繊維長さが２５ｍｍ以上４０ｍｍ以下の鋼繊維よりなり、前記セメント系マトリックス１ｍ3あたり２０万本以上４００万本以下混入されることを特徴とする。【選択図】図１
