Jan 01, 2013· The grinding process impacts the cement manufacture in at least two ways. First, an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions, leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency ...
Mar 08, 2016· The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag making process and its corresponding benefits with respect to the enhanced cementitious properties of the slag. Grinding slag for cement replacement requires only about 25 percent of the energy needed to manufacture Portland cement.
Cement Conservation to Reduce Environmental Impact of Concrete The conservation of cement is the first and most important step in decreasing both energy utilization and greenhouse gas emission. Resource productivity consideration stipulates the deduction of the utilization of Portland cement while meeting the future demands for more concrete.
