Graphene-enhanced cement could help build more durable roads and cities

Northwestern University researchers have added graphene nanoplatelets to cement, resulting in smarter, more durable and highly functional cement.

With cement being the most widely consumed material globally and the cement industry accounting for 8% of human-caused greenhouse gas emissions, civil and environmental engineering professor Ange-Therese Akono turned to nanoreinforced cement to look for a solution. Akono, the lead author on the study and an assistant professor in the McCormick School of Engineering, said nanomaterials reduce the carbon footprint of cement composites, but until now, little was known about its impact on fracture behavior.
