Carbonation Mitigation of the High Volume Admixture Concrete according to Application Method of Carbonation Resistance Material

탄산화 억제제 사용 따른 혼화재 다량 치환 콘크리트의 탄산화 억제

This paper is to investigate the effect of waste cooking oil(WCO) on carbonation resistance of high volume fly ash and blast furnace slag concrete. WCO and paint were applied for carbonation resistance materials. As expected, the application of WCO to the concrete help it reduce carbonation depth remarkably, regardless of mixture types. This may be due to the fact that WCO makes the capillary pore block by activating saponification. It is found that the degree of carbonation reduce due to WCO is much higher than the case by Paint.
