Moini Lab, located in the E-wing of Princeton’s Engineering Quadrangle, focuses on creating stronger 3D-printed concrete and other cement-based materials — which can be more resistant to cracking. Led by Reza Moini, an assistant professor of civil and environmental engineering, the lab’s concrete designs are inspired by patterns found in nature.
