PROBLEM TO BE SOLVED: To provide an ordinary-temperature curable epoxy resin composition capable of hardening quickly not only at ordinary temperature but especially at low temperatures without heating and an adhesive and a repair/reinforcement method of structure using the composition.SOLUTION: An ordinary-temperature curable epoxy resin composition comprises an ingredient (A) an epoxy resin, (B) one or more compounds selected from aliphatic polyamines, alicyclic polyamines and their modified products and (C) a complex of a boron halide and an amine compound, hardens quickly at ordinary temperature, especially in a low-temperature environmental atmosphere, like outdoors in winter, without need of heating, and secures a sufficient usable time. An injection agent, a coating and an adhesion using the composition harden in a low-temperature environmental atmosphere while securing a sufficient usable time. A repair/reinforcement method of a structure using the composition is also provided. |
