The Characterization of Steel Slag by Alkali Activation
This paper presents a characterization analysis of alkaliactivated steel slag. The effect ratio of steel slag and ferronickel slag which are the precursor materials on the compressive strength of the alkaliactivated materials was investigated. The combination of sodium hydroxide solution of 15 moles concentration and sodium silie was used as an alkaline activator.

Slag Cement Questions
Production of slag cement creates a valueadded product from a material—blast furnace slag—that otherwise might be destined for disposal. Not only does the making of slag cement lessen the burden on landfills, but it also reduces air emissions at steel plants through the granulation process (as compared to the traditional air cooling process).
Metal Finishing–What Types of Finishes Are There?
Aug 14, 2021 · Sherardizing is a process used to coat small steel parts such as bolts and washers with a corrosionresistant zinciron alloy. Parts are tumbled in a heated drum containing zinc dust, producing a highly corrosionresistant finish. In highvolume production runs, a barrelfinishing machine is a fast and efficient coating solution.
