Abstract: Microcapsule self-repairing technology is a cutting-edge method to enhance the durability and safety of concrete structures. Starting from the construction materials of microcapsule core and capsule shell, the preparation process, and the repair mechanism, we focus on comparing and analysing the key factors affecting the repair efficiency of the microcapsule, which include the parameters of the microcapsule, the repair triggering mechanism, and the method of evaluating the repair effect, which can be measured from the different dimensions, such as strength recovery, crack closure, and permeability recovery. The repair efficiency can be measured from the strength recovery rate, crack closure, permeability recovery and other different dimensions, and it is significantly affected by the compatibility of microcapsules with the concrete matrix and environmental conditions. This paper summarises the current challenges faced by this technology and provides an outlook on future research directions, with the aim of providing theoretical references for the design and application of high-performance self-repairing concrete. Building upon a review of existing research findings, this paper introduces a critical analytical perspective to examine how variations in testing methodologies affect the comparability of results. Drawing from current studies, it distils design principles and technical roadmaps to guide practical implementation, thereby providing more valuable theoretical reference for the design and application of high-performance self-healing concrete.
