 Concrete is highly susceptible to cracking, which can lead to structural failure if left untreated. To address this issue, researchers have developed methods for introducing self-healing capabilities into concrete. These methods include enhancing the natural process of autogenous crack healing or embedding capsules containing healing agents within the concrete. This review compares the different approaches and evaluates their effectiveness based on the type of agent used and the trigger mechanism employed. It also assesses the properties regained through self-healing. This article was authored by Nellie de Belay and Kim van Tittleboom.
