Summary: This week, host Daniel Raimi talks with Mahmoud Taha, a professor and chair of the Department of Civil Engineering at the University of New Mexico. Taha is an expert on many things related to materials science; in this episode, he talks about cement, which he calls the “magic glue” of construction. Taha and Raimi discuss the greenhouse gas footprint of cement, options for reducing that footprint, how the use of new materials might affect the cost and performance of cement, and government policies that can help spur innovation and speed deployment.
