Understanding the Impacts of Healing Agents on the Properties of Fresh and Hardened Self-Healing Concrete: A Review

Self-healing concrete has emerged as one of the prospective materials to be used in future constructions, substituting conventional with view extending service life structures. As a proof concept, over last several years, many studies have been executed on effectiveness addition self-healing agents crack sealing and healing mortar, while level are still rather limited. In most cases, mix designs were not optimized regarding properties fresh mixture, hardened efficiency, meaning that agent was just added top normal (no adaptations design for introduction agents). A comprehensive review conducted impact (e.g., crystalline admixtures, bacteria, polymers minerals, which some encapsulated microcapsules or macrocapsules) concrete. Eventually, remaining research gaps knowledge identified.
