As project owners and public agencies increasingly require greater sustainability in projects and specify them using LEED and other metrics systems, a “sustainability vs. constructability” challenge must often be resolved for concrete construction. This presentation will explain these challenges and pose resolution protocols. Examples will be used to illustrate each category of issue and the related technical influences will be exposed and discussed. A simple performance testing approach for qualifying candidate materials and proportions will be presented and used to show how these issues can be understood, evaluated, and controlled. Recommendations for project-specific use of this testing approach will be made, and guidance presented on how sustainability of concrete mixtures can be maximized while appropriate performance and constructability is assured.
