CRACK PROPAGATION INHIBITING RESIN COMPOSITION AND CRACK PROPAGATION INHIBITION METHOD
PROBLEM TO BE SOLVED: To provide a crack propagation inhibiting resin composition enabling a simple repair reinforcement method with less workload in construction to be performed on a propagation inhibition of cracks generated in a steel material such as a steel building structure.SOLUTION: The crack propagation inhibiting resin composition containing a normal temperature curing type thermosetting resin and a filler is provided, which contains both of a fibrous filler and a non-spherical particle filler as the filler and has a viscosity of 5 to 2000 Pa s at 25°C at a normal temperature before being cured. The crack propagation inhibiting resin composition contains 20 t 150 pts.wt. of the fibrous filler and the non-spherical particle filler in total at a blend ratio of formula (I)(blended amount of the non-spherical particle filler/blended amount of the fibrous filler=1 to 10) with respect to 100 pts.wt. of the normal temperature curing type thermosetting resin and has an average particle diameter of the non-spherical particle filler of 1 to 80 μm. The crack propagation inhibiting resin composition reinforces the steel structure by applying the resin composition onto a crack place of the steel structure and curing the resin composition.SELECTED DRAWING: None
