We have already surveyed members of the American Concrete Institute, National Ready Mixed Concrete Association and American Society of Concrete Contractors for input on their experiences -- both good and bad -- with "green" concrete. Also, "green" concrete mixtures will be tested and the data presented in the Guide to provide information that is usually proprietary and not available to the industry or to the public. This data will supplement, support and be used to illustrate the construction challenges of "green" concrete. Companies contributing to this phase of the work and as an advisory team include U.S. Concrete (concrete producer), Tipping + Mar (structural engineer), Webcor Builders (contractor) and BASF (admixture manufacturer).
Look for updates as we follow this project through to completion.
