파이프 구조를 활용한 폴리머 콘크리트의 진동 특성 개선 연구

초록

The purpose of this study was to improve damping performance of polymer concretes. The polymer concretes consisted of epoxy monomer, hardener and aggregates. To improve damping characteristics of polymer concrete, acryl pipe structure was inserted in the polymer concrete. A transfer function method was imposed to measure the dynamic stiffness and loss factor by obtaining impact response of the concrete specimens. Comparing the measured dynamic properties of the polymer concretes, proper pipe structure was discussed. Finally, mechanical and economical effects of inserting pipe were compared with cement and normal polymer concretes.
