PROBLEM TO BE SOLVED: To provide a method for suppressing cracking of a concrete structure caused by change in ambient temperature, the concrete structure being susceptible to cracking, and to provide a method for particularly preventing cracking of the concrete structure caused by change in the ambient temperature after injection of a filler, by using the characteristics of the filler once injected into a gap in the concrete structure. SOLUTION: There is provided a method for suppressing cracking of the concrete structure, according to which the filler formed of a room temperature curing resin composite is injected into the gap in the concrete structure. Herein, the employed room temperature curing resin composite should have an elongation percentage of 200% or more when cured, and adhesive strength to a dry mortar cured body of 5 N/mm<SP>2</SP>or less. Thus, the resin composite injected into a hardened layer of the stratum functions to release thermal cracking stress generated at the gap or in the vicinity of the gap. COPYRIGHT: (C)2003,JPO |
