SCA has posted for free download a calculator with which concrete producers can quantify and interpret cradle-to-gate life cycle assessments (LCA) reflecting the environmental impact of mixtures with and without slag cement. Calculations are based on the industry-average Environmental Product Declaration (EPD) for ready mixed concrete that incorporates industry-average EPDs for slag cement and portland cement in the United States. The calculator also allows users to evaluate how different concrete mixtures affect whole building impacts based on a typical case study project.
