PROBLEM TO BE SOLVED: To provide a highly durable fiber sheet for preventing a concrete structure from peeling off as a fiber fabric for use in repairing/reinforcing the concrete structure when a possibility of concrete peeling-off occurs in the concrete structure. SOLUTION: The fiber sheet for preventing a concrete structure from peeling off comprises Vinylon fiber with a strength of 5-15 cN/dtex, an elongation at break of 5-20% and a Young's modulus of 10-27 GPa. This fiber sheet has a breaking strength of≥1,500 N/30mm and an elongation at break of 6-22% at least in one direction thereof. COPYRIGHT: (C)2004,JPO&NCIPI
