PPCC(Polymer-portland-cement concrete)를 이용한 방수 및 부착 성능 평가

Several materials using polymer-portland-cement concrete have developed to have not only strength of attachment with body ,but also waterproof function and strong anti-sodium chloride properties. Especially, in case of railway, unlike other public transportation, it is very difficult to doing the repair and reinforcement work of structure during service time. Therefore, the development and study of materials having characteristics of structural strength, unification behavior with body, and resistance of crack are very important. Accordingly, the characteristic of material of polymer based concrete is indicated compared with the experiment and analysis through this study, and suggested application to railway tunnel, bridge, and concrete track structure.
