The Slag Cement Association (SCA) is proud to announce version 3.0 of its Life Cycle Assessment Calculator for slag cement is now available on for use on the SCA website, slagcement.org. “The entire industry is looking for ways to convey the environmental impact of SCM’s in concrete mix design,” says Drew Burns, Executive Director, Slag Cement Association, “This calculator provides a way to assist decision makers in understanding the sustainable benefits of slag cement use.” Slag cement is a recovered material from the iron production process, and therefore reduces the environmental impact of concrete mixtures. What’s more, slag cement is very effective in reducing permeability and increasing concrete’s durability. Slag Cement Life Cycle Assessment Calculator The SCA commissioned the Athena Institute to produce its Ready Mixed Concrete Life Cycle Assessment (LCA) Calculator for Slag Cement - Version 3.0 to show the environmental impacts of using slag cement in ready mixed concrete. The LCA calculator allows users to enter custom concrete mixes and then substitute varying amounts of slag cement through a simple dashboard interface.
By selecting a preset mix or entering the details of a custom mix, the calculator allows users to increase or decrease the percentage of slag cement and calculate LCA results in real time. The tool also allows users to compare custom mixes against region-specific industry average mixes and substitute these mixes into a generic whole building to calculate cumulative whole-building results. The calculator can be accessed on the SCA’s website.
Environmental Product Declaration The growing need to reduce the carbon impact of concrete has led the SCA to create an Environmental Product Declaration (EPD) for slag cement. The recently updated EPD provides quantifiable environmental data on the materials, transportation, and processing impacts in the production of slag cement. View the full EPD here: EPD on Slag Cement (2021) PCR for Slag Cement (2020) For more information on the sustainability benefits of slag cement, visit www.slagcement.org/sustainability.
