The present invention relates to a repair method for extending the life of concrete, and more particularly, a repair method for extending the life of concrete, which exhibits high work efficiency and adhesion property, thereby stably repairing cracks and interlayer joints due to deterioration and aging of concrete in a short time, and exhibits excellent mechanical strength and waterproofing property, thereby continuously preventing deterioration and aging of concrete after repair. The repair method for extending the life of concrete comprises a step of removing an aged and deteriorated portion of concrete, a step of removing foreign materials, a step of applying an anticorrosive on an exposed rebar portion, a step of restoring the aged and deteriorated portion of the concrete, a step of applying a high-elasticity coating repair material, a step of hardening and drying the high-elasticity coating repair material, a step of reapplying the high-elasticity coating repair material to complement a defective portion, and a step of applying a concrete finishing material.
본 발명은 콘크리트 수명 연장을 위한 보수공법에 관한 것으로서, 보다 상세하게는, 높은 작업 효율성 및 접착성을 나타내어 콘크리트 열화 및 노화로 인한 균열 부위 및 층간 조인트 부위를 단시간 내에 안정적으로 보수할 수 있으며, 우수한 기계적 강도 및 방수성을 나타내어 보수 후에도 콘크리트의 열화 및 노화를 지속적으로 방지할 수 있는, 콘크리트 수명 연장을 위한 보수공법에 관한 것이다.
