What are the enviromental benefits of using slag cement?
Production of slag cement creates a value-added 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). Use of slag cement in concrete reduces the environmental impact of concrete by:
The Environmental Protection Agency recognizes the environmental benefits of using slag cement in concrete. It has classified slag cement as a “recovered” product under the Resource Conservation Recovery Act (RCRA), and has issued a procurement guideline requiring its specification on most federally-funded projects.
