Tunstall Materials Research Group

about our group

We work to improve construction materials using a materials science approach–understanding how processing affects microstructure and how microstructure affects macroscopic properties. Through an understanding of the fundamental science that controls the material behavior, we can make systematic changes to control engineering properties. Our current focus is to improve the durability and sustainability of cement-based materials.

Why cement-based materials?

Concrete is the most consumed material in the world, second only to water. It is cheap, durable, malleable, and made from raw materials found all throughout the world. Unfortunately, its popularity also makes it responsible for 8% of global CO2 emissions. The carbon footprint is primarily from the production of cement, during which limestone (calcium carbonate) is converted to free lime (calcium oxide), which releases CO2. Since the CO2 emissions are tied to the cement’s composition, it’s difficult to reduce the carbon footprint without fundamentally changing the basic building block of concrete. Innovative solutions are needed to decrease concrete’s carbon footprint without sacrificing its performance. Our group exists to drive these solutions.
