The National Ready Mix Concrete Association has updated its industry average environmental impacts for concrete.
The aim is to provide product transparency within green building standards. The second version of the NRMCA Industry-Wide (IW) Environmental Product Declaration (EPD) and Benchmark (Industry Average) Report discloses the environmental impacts of concrete manufacturing for a wide range of concrete products.
The updated document includes additional member companies, concrete plants, and concrete mixes. Similar to the original, the new NRMCA IW EPD lists impacts for concrete ranging compressive strengths from 2,500 psi through 8,000 psi, covering most concrete used in residential, commercial, and public construction.
A wide range of products are covered for each strength class; from 100% portland cement mixes to mixes with over 50% replacement with fly ash and slag cement. Lightweight concrete mix designs have also been added in the new version.
The IW EPD now includes 88 companies, 2,519 plants, and 72 mixes offering enhanced data for baselines and resulting in significant national coverage and production. LEED v4 includes a credit that encourages a project team to use building materials that have EPDs.
