Applicability of Basic Oxygen Furnace Slag as a

Several experiments concerning workability, compressive strength and dimensional stability of concrete made with basic oxygen furnace slag were conducted for investigating the possibility of the use of basic oxygen furnace slag as a concrete aggregate. The concrete made with weathered slag showed a much higher slump for a given mix proportion than natural aggregate concrete and the concrete prepared

Evaluation of Basic Oxygen Furnace (BOF) material

2016-7-15  Basic Oxygen Furnace (BOF) slag has many prismatic angles, is massive, and has a high hardness that meets the requirements of the aggregate used in asphalt concrete. BOF has a higher proportion of CaO but a lower proportion of SiO 2 than natural (gravel) aggregate (NA) because CaO is a lipophilic molecule while SiO 2 is a hydrophilic molecule, so BOF can be more closely integrated with the asphalt.
