Abstract

The issues concerning the stability and durability of concrete structures have garnered increasing attention. This study, through theoretical analysis and experimental investigation, explores the application of epoxy resin adhesives in self-healing concrete. A three-point bending test was conducted on the self-healing system, employing C30 concrete as the substrate, with glass double tubes 80 mm in length and 1 mm in wall thickness, possessing an inner diameter of 10 mm, serving as the resin reservoirs, and modified epoxy resins serving as the healing agents. The experimental data indicate that the healing system has a certain degree of strength recovery effect on the concrete matrix, yet the recovery rate is suboptimal, and there are areas for improvement. Furthermore, this paper investigates the optimization of the epoxy resin adhesive formulation and its efficacy in self-healing concrete applications.
