Quality Properties of Blast Furnace Slag Brick Using the Recycled Fine Aggregates Depending on Waste Oil and Curing Method

폐식용유 혼입 및 양생방법에 따른 순환잔골재 사용 고로슬래그 벽돌의 품질특성

This study reviewed the effect of W/B, WO and curing method on the quality properties of RA using the BS brick under the zero cement condition. compressive strength was found to show an increasing trend as W/B increased, but to show a improvement in case steam curing was conducted, showing a higher increase at 1 day age in comparison with 7 day age. In addition, the compressive strength on the mixing of WO didn't show any specific trend. The absorption tended to decrease as W/B increased and met the less than 10% regulation value at 30~35% W/B in case WO was used, there appeared a decrease attributable to capillary pore filling effect due to saponification. On the other hand, compressive strength increases, th absorption showed a gradually decreasing tendency.
