Abstract:
Steel furnace slag, a by-product of the steelmaking process, can be used as a portland cement replacement in production of concrete masonry units (CMUs). Even though steel furnace slag lacks cementitious or pozzolanic properties, it gains strength when exposed to CO2 in the presence of water. The article discusses technology for manufacturing CMUs using steel furnace slag as a total cement replacement.
