PROBLEM TO BE SOLVED: To provide a reinforcement structure of concrete and a reinforcement method therefor, capable of improving bending fatigue resistance and shear capacity of concrete by replacing a part of the concrete with an expansive admixture and introducing prestress to the surrounding concrete.SOLUTION: The invention relates to a reinforcement structure of concrete, for preventing destruction due to the act of external force. The reinforcement structure 1 of concrete applying the present invention includes a core part 2 formed by drilling concrete 5, and an expansive admixture 4 filled in the core part 2. The expansive admixture 4 expands after being filled in the core part 2, causing the concrete 5 surrounding the core part 2 to be pressed, and thus produces a state in which a compressive force P is applied on the concrete surrounding the core part 2.SELECTED DRAWING: Figure 9 |
