摘要： PROBLEM TO BE SOLVED: To provide a method of repairing a crack in mortar or concrete at a radioactive waste disposal plant in which a large effect on suppressing leaching is derived entirely against cracks up to deep portions by using an injection material which can be injected up to deep portions of fine cracks of 0.5 mm or less in mortar or concrete at a radioactive waste disposal plant.SOLUTION: An injection material containing ultrafine particles of spherical silica and water is injected into a crack in mortar or concrete at a radioactive waste disposal plant, and the ultrafine particles of spherical silica of the injection material filled from a surface layer up to deep portions of the crack are hardened by reaction with calcium leaching from the mortar or concrete. The concentration of the ultrafine particles of spherical silica is preferably more than 60% in the injection material.
