| Research Abstract |
In this research, the self-healing phenomenon and secondary phases of newly-formed products based on concrete structures were investigated in historical structures. Moreover, in order to understand the precipitation conditions of calcium salts in the cracks, morphology, and the shape and size of re-hydration products in the old concrete, microscopy and SEM(EDS)analyses were conducted. And then, new repair methods based on crack self-healing technologies using cementitious materials were suggested in order to prevent water leakage in civil infrastructures.
