PROBLEM TO BE SOLVED: To provide a curable composition for repairing an underwater structure that penetrates autonomously into a deepest part of a crack and retains a repair effect with sufficient durability, even with a minute crack formed underwater that has been difficult to repair fully by injecting a publicly known conventional resin-based injection material.SOLUTION: A curable composition for repairing an underwater structure includes water, cement as a principal material, an underwater-non-separable admixture, and a weighting material made of inorganic particles. The weighting material has a particle size distribution such that a ratio of particle sizes under 0.1 mm is 90% or more and a ratio of particle sizes under 0.05 mm is 80% or more. Furthermore, an absolute specific gravity of the weighting material is greater than an absolute specific gravity of the cement as a principal material.SELECTED DRAWING: Figure 1 |
