| Abstract |
This study aimed for the development of the cementitious joint with easy-disassembly and attempted the design for disassembly that used mechanism of the microwave heating. The purpose of this study is to choose a susceptor, which helps raise the heating efficiency with microwave heating, and to evaluate heating effectiveness with microwave heating by analysis of the temperature elevation characteristics. As a result of this study, excellent temperature elevation characteristics is showed by using ferric material as susceptor of cementitious modifier considering the heating efficiency of microwave heating. In addition, iron oxide powder shows the heating efficiency of microwave better than pure iron powder. For that reason, iron oxide powder is very suitable as susceptor for cementitious modifier. The cementitious modifier which used iron oxide powder was able to reach in the temperature that is possible of the fragility of the cementitious material by microwave heating, less than 30 seconds at 700W and 20 seconds at 1800W in the case of S/B1.0, thickness 1mm in oven dry condition. |
