Ready-Mix Concrete Overdesign and Sustainability: Moving in Opposite Directions
Ready-mixed concrete producers often overdesign their mixtures above the required average strength to ensure field performance despite the variability of several factors that are outside of a producer’s control. Since failure to meet required strength can lead to structural problems, leaving a concrete producer potentially responsible, concrete producers often overdesign to self-protect against such liability. Several reasons can cause excessive overdesign including, but not limited to, compensating for improper field practices like excessive water addition or the need for early-age strength requirements; necessary to speed up construction processes such as formwork removal.
