%X Using C30 concrete prefabricated cracks, fast curing epoxy resin grouting material is used for crack grouting reinforcement. After 3 days, core samples are taken for compressive strength and splitting tensile strength testing. Core samples are selected from the crack containing and crack free areas for testing, and the reinforcement effect is compared after 3 days of crack grouting. The results showed that the compressive strength of the 3-day core sample was 38.1 MPa for the cracked core sample and 37.2 MPa for the intact core sample; The 3-day splitting tensile strength was 4.05MPa for the cracked core sample and 3.94MPa for the intact core sample, achieving the goal of a 3-day strength not lower than the design value (intact core sample) after crack treatment.
