CURABLE COMPOSITION FOR REPAIRING UNDERWATER STRUCTURE, AND REPAIR METHOD FOR UNDERWATER STRUCTURE USING THE SAME
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
【課題】従来公知の樹脂系の注入材の注入によっては、十分な補修が困難であった、水中に存する微細な亀裂等に対しても、亀裂の最深部まで自律的な浸透が可能であり、十分な耐久性をもって補修効果を保持しうる水中構造物補修用の硬化性組成物を提供すること。【解決手段】水と、主材セメントと、水中不分離性混和剤と、無機粒子からなる加重材と、を含有し、前記加重材は、粒径０．１ｍｍアンダーの割合が９０％以上で粒径０．０５ｍｍアンダーの割合が８０％以上の粒度分布を有し、該加重材の真比重は、前記主材セメントの真比重よりも大きい水中構造物補修用の硬化性組成物とする。【選択図】図１
