HIGH PERFORMANCE FIBER REINFORCED CEMENTITIOUS COMPOSITE
PROBLEM TO BE SOLVED: To provide a high performance fiber reinforced cementitious composite (HPFRCC) having preferable strength in resistance to shear fracture after generation of cracks while keeping deformability being the original property of the HPFRCC.SOLUTION: The high performance fiber reinforced cementitious composite (HPFRCC) is provided in which polymer fiber having an aspect ratio of 30 or more and a tensile strength of 1000 MPa or more and 3000 MPa or less and stiff fiber having an aspect ratio of 5 or more and 30 or less and an elastic modulus of 19.7 GPa or more and 21.6 GPa or less are randomly dispersed and blended in a matrix. The polymer fiber is contained in the matrix at a blending ratio of 1 volume % or more and 3 volume % or less. The stiff fiber is contained in the matrix at a blending ratio of 0.1 volume % or more and 2.2 volume % or less.
【課題】複数微細ひび割れ型繊維補強セメント複合材料（ＨＰＦＲＣＣ）について、ＨＰＦＲＣＣの本来の特性である変形能を維持したまま、更に、クラック発生後の耐せん断破断性についても好ましい強度を有するＨＰＦＲＣＣを提供すること。【解決手段】複数微細ひび割れ型繊維補強セメント複合材料（ＨＰＦＲＣＣ）を、アスペクト比が３０以上で、且つ、引張り強度が１０００ＭＰａ以上３０００ＭＰａ以下であるポリマー繊維と、アスペクト比が５以上３０以下で、且つ、弾性係数が、１９．７ＧＰａ以上２１．６ＧＰａ以下である剛繊維と、がマトリクス中にランダムに分散配合されており、前記ポリマー繊維は、前記マトリクス中に１体積％以上３体積％以下の配合比で含有されており、前記剛繊維は、前記マトリクス中に０．１体積％以上２．２体積％以下の配合比で含有されているＨＰＦＲＣＣとする。【選択図】図２
