The MIT Electron-conductive Cement-based Materials Hub (EC^3 Hub), an outgrowth of the MIT Concrete Sustainability Hub (CSHub), has been established by a five-year sponsored research agreement with the Aizawa Concrete Corp. In particular, the EC^3 Hub will investigate the infrastructure applications of multifunctional concrete — concrete having capacities beyond serving as a structural element, such as functioning as a “battery” for renewable energy.
