Abstract:
Overdesigning concrete mixtures for compressive strength results in an increased carbon footprint due to much higher cementitious materials content and added construction costs. This article discusses some of the reasons why concrete mixtures are overdesigned and offers recommendations to avoid unnecessarily high overdesigns.
