Utilization of steel slag for Portland cement clinker ...

01/04/2008  However, the C 3 S content in steel slag is much lower than in Portland cement. Thus, the steel slag can be regarded as a weak Portland cement clinker. The main problem with using steel slag in civil engineering is the possible presence of free lime, especially large-sized components of heated undissolved limestone, because when it hydrates, its volume increases and this swelling can lift the ...

Ground granulated blast-furnace slag - Wikipedia

Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blastfurnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete. Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement,
