METHOD FOR REPAIRING CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for repairing a concrete structure with excellent workability because of the use of a lightweight material, simultaneously performing cross-sectional restoration and a separation preventive measure and maintaining a reinforcing effect over a long period of time. SOLUTION: This method of repairing the concrete structure comprises the steps of sticking a mesh fiber reinforcing material with the seam spacing of 10 mm or more and a longitudinal-lateral tensile strength of 400 N/25 mm or more to the repaired face of the concrete structure, spraying cement mortar to the mesh fiber reinforcing material in the cement mortar, and hardening the surface of the cement mortar after smoothing it.
