A companion to New Technology-Based Approach to Advance Higher Volume Fly Ash Concrete with Acceptable Performance, published in September 2008 by the RMC Research & Education Foundation, provides additional insight on supplementary cementitious material-bearing mix designs. Based on National Ready Mixed Concrete Association Research Laboratory tests, it demonstrates that ready mixed concrete producers can use a greater amount of fly ash in concrete mixtures while maintaining strength and performance and still being able to attain the early-age strengths required for the application. The new guide will assist the entire construction team in their efforts to integrate more fly ash-a recycled material in the minds of green-building practitioners-in a variety of projects.

This guide is a terrific tool for the concrete industry to effectively implement the original study findings, said RMC Research & Education Foundation Chairman George Gregory. Findings from studies such as the Fly Ash report make a greater impact when accompanied by materials that will assist those in the field with proper application. The inclusion of the accompanying guide was a compelling factor for the Board of Trustees when they approved funding for this project.

Both the original study and the new Guide for the Construction Team are available for download from the Foundation’s website, www.rmc-foundation.org, and are also available as part of the Foundation’s Research Supporting Sustainable Development CD.
