Published purpose

Ground granulated blast furnace slag (GGBFS), a byproduct of iron production, has seen wide adoption by the concrete industry. On the other hand, Basic Oxygen Furnace (BOF) slag, another abundantly available byproduct of steel production, has seen practically no use as Supplementary Cementitious Materials (SCM). Inkas and U of T undertook the development of the technology of converting BOF slag into reactive SCM using mechanical calcination (MC). The positive results of the initial experiments suggested use of such method for processing BOF steel slag and proposed solution to a pressing problem of metallurgical waste utilization by converting it into reactive SCM that can be further used in concrete production.
