To ensure that a #concrete mixture meets its required strength, producers often formulate the mixture to have more strength than is specified. This practice, called overdesign, raises the mixture's cost and embodied greenhouse gas (GHG) emissions. A new research brief from the MIT Concrete Sustainability Hub suggests that overdesign optimization can decrease embodied GHG without sacrificing safety or performance. Elsa Olivetti, one of the brief's authors, is a mission director for the MIT Climate Project and a professor in the MIT Department of Materials Science and Engineering (DMSE). #ghg #carbon #construction #MIT #cement
Concrete is typically designed to be stronger than required to account for natural variability and ensure acceptance at the job site. By narrowing this gap through greater quality control and innovation, we can cut excess material use and save more than 80kg of CO?-equivalent per cubic meter of concrete.
