Abstract
Cracks threaten the durability of concrete structures, as the ingress of the aggressive substances into the matrix through these cracks can cause concrete degradation. Thus, cracks may propagate and result in the exposure of the reinforcement to environments. Total or partial failure of the structure may happen after the embedded steel begins to corrode or oxidize, leading to a reduction of the in-service durability of concrete. For that reason, different measures have been undertaken to minimize the size and number of cracks in concrete. Developing an appropriate concrete mix design, carefully selecting raw materials, choosing a proper curing regime and having an appropriate structural management of operation are among these measures. Despite the fact that it is virtually impossible to make cracks disappear, cracks can be controlled or significantly reduced. Despite of this, it is difficult to repair the invisible or inaccessible cracks. Consequently, the self-healing of cracks in concrete is indispensable and would contribute to a longer service life of concrete structures..
