Resumen
The durability of buildings is impaired when certain conditions or environments promote deterioration of the concrete, compromising the performance and integrity of the structure. Cracks are pathological manifestations of degradation agents, such as chlorides and sulfates. Reinforced concrete requires maintenance operations that, in appropriate periods, intervene in actions that increase or maintain performance in service. Self-healing concrete is an alternative for reducing expensive maintenance and repair actions, but its durability needs to be investigated. The objective of this research is to investigate the durability of self-healing concrete when subjected to degradation agents. The proposed methodology is the mapping of research published in Brazilian and international literature on the durability of self-healing concrete exposed to chlorides. The results showed that the self-healing concrete maintains its durability when exposed to chloride. However, it is not yet possible to certify its lifespan over time.
Palabras claves
