Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a metallic fiber for reinforcing cement hardened body which is used for reinforcing a cement hardened body (particularly having high strength of ≥100 MPa compressive strength), can be easily and uniformly deipersed in a short period of time without being entangled with each other in kneading, has sufficient adhesiveness to a base material and can improve toughness and further mechanical strength such as bending strength of the cement hardened body. SOLUTION: As for the metallic fiber 1, its diameter is ≤0.3 mm, its tensile strength is 1.0-3.5 GPa and its shape is made spiral. The spiral shape is defined so that it has a cycle B >1.0 time and ≤5.0 times the fiber length and has an amplitude A 0.5-3.0 times the fiber diameter. The aspect ratio of the metallic fiber 1 is 20-200. COPYRIGHT: (C)2008,JPO&INPIT
