The developed fast - curing epoxy grouting material was tested for properties based on GB/T 2567 - 2021 and JC/T 1041 - 2007 . Tests included compressive strength (3 - day, 7 - day), tensile strength (7 - day), working time, and bond strength with concrete (7 - day, dry and wet surfaces). Results showed the material met or surpassed technical requirements. Notably, the 3 - day compressive strength reached 51MPa, exceeding the design standard for C40 concrete and common dam concrete.
