Studies from Argonne National Laboratory Provide New Data on Materials Science

June 24, 2014



By a News Reporter-Staff News Editor at Physics Week -- Researchers detail new data in Materials Science. According to news originating from Argonne, Illinois, by VerticalNews correspondents, research stated, "Synchrotron nanoprobe X-ray fluorescence maps show for the first time discrete iron-rich, titanium-rich and manganese/silicon-rich particles present in blast furnace slag grains, and these particles remain intact when the slag is used as a precursor for alkali-activated slag (AAS) binders."

Our news journalists obtained a quote from the research from Argonne National Laboratory, "These particles appear to be entrained during slag production, and remain stable under the reducing conditions prevailing during alkali-activation. There is no evidence of chemical interaction between these particles and the AAS binder, which mainly comprises calcium silicate hydrates."

According to the news editors, the research concluded: "These results are important for the understanding of iron chemistry in AAS, and the potential reactivity of metallic and other redox-sensitive species within AAS binders."
