Steel manufacturing produces steel slag as a by-product; this material has cementitious properties due to its highly reactive minerals (calcium silicates and calcium aluminoferrite) to produce slag cement which by partially replacing Portland cement results in reducing greenhouse gas emissions by 70%.
The slag grinding is done when the slag is milled to very fine particles marketed as ground granulated blast furnace slag (GGBFS).
The GGBFS’ cementitious properties make this material a proper replacement for ordinary Portland cement, and it is categorized as a high-quality supplementary cementitious material.
Various grinding systems, like a vertical roller mill or a ball mill, can be used to produce GGBFS according to specifications. PEC Consulting can help determine the best grinding system and conceptualize the most efficient plant design.
