ABSTRACT
Among all investigated approaches to obtain self-healing properties in concrete, autonomous healing of cracks through release of embedded polymer-based healing agents, seems a very promising approach. However, a suitable healing agent is needed to assure that also upon multiple crack formation, all cracks can be healed. For this purpose methyl methacrylate seems a suitable agent as it can create a very strong bond with the cementitious matrix. This will assure that after autonomous crack repair, later cracks appear at another location, where the self-healing mechanism is still intact and can thus still cause release of healing agent. As some problems with regard to the methyl methacrylate healing agent were found in previous research, these were tackled within this study by following three different approaches. The most promising approach(es) were selected for further use with regard to self-healing of concrete.
