Development of a Method to Make Existing Reinforced Concrete Structures Fragile, using Theprinciple of Induction Heating

In existing buildings, demolitions and new constructions are performed to respond to the rapidly changing needs of society regardless of the structure’s performance. In terms of the demolition ability of the construction materials, for the demolition ability at the early stages of design when remodeling is considered, technologies that reduce the energy required for the recycling process and have minimal environmental impact are necessary. Currently, in each industrial sector in the 3R (Reduce, Reuse, Recycle), considering the materials designed for this degradation is an important issue. These material designs are introduced in many industry sectors (especially in the electronics sector) for easy maintenance, upgrade, and recycling after the demolition work. Moreover, demolition ability is considered to be an important issue in the facilities field. In this study, the feasibility of the induction heating method as a demolition method was investigated. First, using an induction heating device, the temperature changes in the rebar were measured according to the power rate. Then, the heated rebar was used to weaken the concrete structure. In the process, the demolition ability of induction heating method was evaluated.
