Japanese Patent JP6218239

B2

PROBLEM TO BE SOLVED: To safely perform a repairing operation from the lower part without increasing to a storage shed.SOLUTION: Provided is a curable filler M comprising a curing agent, a chemical admixture, an aggregate, a retardant, a liquid resin and water, and in which working life is 30 to 60 min, compressive strength for the material age of 3 hr is 10 N/mm, the coefficient of water absorption is 5% or lower and adhesive performance is 1N/mmor higher. The curable filler M is put and placed on a patch 5, the patch 5 placed with the curable filler M is pressed against the lower face of the part 4 to be repaired from the lower part of the part 4 to be repaired of the storage shed 3, the curable filler M is extruded to the upper face of the storage shed 3 from a gap of a crack, a hole and a beverage, and the patch 5 is supported as being pressed against the lower face of the part 4 to be repaired. When the curable filler M reaches condensation end from condensation start, the patch 5 is adhered to the part 4 to be repaired.SELECTED DRAWING: Figure 6
