With the world facing a climate crisis due to the effects of anthropogenic CO2 emissions and associated global warming, key scientific research is required to aid reducing the impact society has on the environment.
The Sustainable Cements Group (SCG) at Princeton University is a multi-disciplined research group addressing the sustainability challenge facing cementitious materials. The main focus of the group centers on alkali-activated materials, a class of low CO2 concrete with the potential to significantly reduce CO2 emissions associated with the cement industry. Other areas of research interest in the group include amorphous carbonates, layered materials and the development of modeling tools.
Assistant Professor Claire White leads the Sustainable Cements Group (SCG) at Princeton University. The group is situated in the Department of Civil & Environmental Engineering and the Andlinger Center for Energy and the Environment.
