Autogenous self‐healing of concrete: Experimental design and test methodsA review

Cracks in concrete structures can serve as pathways for aggressive chemical substances that lead to a progressive deterioration of the cement stone well reinforcement, affecting load capacity, service life and useability structures. However, reinforced exhibit an intrinsic ability heal cracks, defined autogenous self-healing. This effect includes precipitation calcium carbonate presence water CO2 is accompanied by continued hydration, swelling, mechanical blocking crack pathway. Experiments led inclusion sealing self-healing Eurocode 1992–3 retaining despite code restrictions, shows limited effectiveness practice. indicates need further research provide engineers with reliable design rules. Therefore, this study aims giving broad literature review on state-of-the-art knowledge self-healing, boundary conditions, consensus, controversy processes factors influencing efficiency Regarding transferability laboratory results real constructions, materials, initiation techniques, experimental concepts, methods assessing are discussed recommendations future experiments set.
