A Study on the Evaluation of Carbonation Resistance of Fire Damaged Fiber-Reinforced High Strength Concrete with the Type of Surface Repair Materials

섬유혼입 고강도 콘크리트의 화재 후 표면보수재료의 종류에 따른 중성화 저항성 비교·평가에 관한 연구

In this study, after applying a silicate-based impregnation and polymer-based coating to fire damaged high strength concrete, carbonation resistance was evaluated to compare and evaluate the carbonation depth according to the type of surface repair materials. As a result of the experiment, it was confirmed that the carbonation resistance was increased in the case of the concrete with the surface repair materials compared to the control specimen without the surface repair materials. In particular, in the case of the polymer-based coating agent, it was confirmed that the carbonation hardly progressed.
