Abstract:
The Eco Concrete Competition was proposed by ACI Committee 130 in 2014 with the goal of promoting mixture design as an important aspect of concrete sustainability. The rules require students to design two mixtures with the same water-binder ratio (w/b) but different constituents: the base case scenario (BCS) and the alternative case scenario (ACS). Teams are evaluated based on comparisons of the environmental impacts of the BCS and ACS mixtures.
