PROBLEM TO BE SOLVED: To provide a repair material rapidly cured, high in strength, having no problems of contraction and neutralization, furthermore having a low water permeability, and having excellent durability due to such properties, and a repair method and a reinforcing method using the repair material.SOLUTION: A ceramic composition comprising 36 wt.% of calcium silicate, 34 wt.% of potassium dihydrogenphosphate, and 30 wt.% of magnesium oxide is mixed with 100 pts.wt. of dry mix in a ratio of 36 pts.wt., and water is added to the ceramic composition and the dry mix in a moisture ratio of 20% and they are kneaded to form a slurry. The slurry is filled in a pot-hole 13 and cured to form a repair material 14. |
