유지류 도포가 고로슬래그 다량 치환 콘크리트의 염해 저항성에 미치는 영향

The purpose of this study was to investigate the effect of application of various kinds of oil on resistance to chloride attack of the concrete incorporating high volume blast furnace slag(BS). The concrete incorporating 60% of BS with 60% was fabricated. Silicate alkali recovery agent, bio diesel, emulsified cooking oil and emulsified bio diesel were adopted for surface application. Resistance to chloride attack was measured for 4 weeks. Test results indicated that application of BD on the surface of concrete resulted in an improvement of resistance to chloride attack.
