Accordingly, if furnace slag is grounded into granulars (ground granulated basic oxygen furnace slag; GGBOS), it can be mixed with GGBS and replace the remaining 20% or 30% of the Portland cement as cementitious material. Consequently, an increased amount of wasted furnace slag can be processed while further reducing cement usage.
