The objective of this paper is to investigate the effect of spreading time of waste cooking oil (WCO) on durability of high volume blast furnace slag concrete. Carbonation and resistance to chloride attack were measured according to spreading time of WCO. WCO was spreaded on the surface of the concrete with different curing condition after demolding. Blast furnace slag with 60% was incorporated into concrete with 45% of W/B. Test results indicated that carbonation and penetration resistance of chloride attack had favorable results with the condition of 28days water curing and spreading WCO.
