A fundamental study was carried out to develop a kind of smart concrete that has a self-healing system that incorporates a heating device. Self-diagnosis composite is employed as the heating device used to heat up cracked parts in the concrete. This heating device and a pipe made of heat-plasticity organic film containing a repair agent are embedded in the concrete. The film is melted through suitable heating. Selective heat around a crack can melt the film to allow the repair agent to fill up the crack and harden the repair agent in the crack. Three-dimensional thermal analysis and an experimental study were carried out to confirm the proposed method.
