UCLA Associate Professor and Henry Samueli Fellow, Civil and Environmental Engineering
He has a concrete solution for climate change.
Carbon dioxide is a major component of the greenhouse gases that trap heat in Earth’s atmosphere. Many scientists search for ways to reduce CO2 emissions. But Gaurav Sant, UCLA associate professor of civil and environmental engineering, is making industrial pollution part of the solution. Sant and an interdisciplinary team of collaborators have invented a sustainable concrete for use as a building material. Thus far, the cement-like material has only been produced at laboratory scale, using 3-D printers to shape it into tiny cones. Now the UCLA inventors are tackling the challenges of industrial scale. “We’re not just trying to develop a building material,” Sant says. “We’re trying to develop a process solution, an integrated technology which goes right from CO2 to a finished product.”
