Abstract
It has been estimated that, in Europe, 50 % of the annual construction budget is spent on refurbishment and remediation of the existing structures (Cailleux, 2009). Therefore, self-healing of concrete structures, which are very sensitive to cracking, would be highly desirable. In this research, encapsulated healing agents were embedded in the concrete matrix in order to obtain self-healing properties. Upon crack appearance, the capsules break and the healing agent is released, causing crack repair. It was found that more than 80 % of the original strength and 60 % of the original stiffness could be regained after self-healing. It was also found that the water permeability could be reduced by a factor 100-10000 due to autonomous crack healing.
