Document Type and Number:
Japanese Patent JP2023004222
Kind Code:
A
Abstract:
To improve the reinforcing effect of a concrete structure while reducing the number of laminated fiber sheets.SOLUTION: A reinforcing structure 10 has a reinforcing layer 12 in which a primer layer 20 and a resin mortar layer 50 are formed in this order on a surface 90A of a concrete structure 90, with a fiber sheet 40 including a reinforcing fiber 42 bonded to the resin mortar layer 50. A resin mortar 52 of the resin mortar layer 50 satisfies the following conditions (1) to (3): (1) Young's modulus should be 3000 N/mm2 or more; (2) Rupture strain should be 0.5% or more; (3) Shear bond strength should be 0.5 N/mm2 or more.SELECTED DRAWING: Figure 1
