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.
Recent paper on impact of alkalis, and their ordering, on the stability of C-S-H: Symmetry-induced stability in alkali-doped calcium silicate hydrate in J. Phys. Chem. C
Check out our latest paper on the reaction mechanisms occurring during alkali-activated of slag: In situ quasi-elastic neutron scattering study on the water dynamics and reaction mechanisms in alkali-activated slags, in Phys. Chem. Chem. Phys.
Our paper, Drying-induced Atomic Structural Rearrangements in Sodium-based Calcium-alumino-silicate-hydrate Gel and the Mitigating Effects of ZrO2 Nanoparticles, in Phys. Chem. Chem. Phys. was named as a HOT manuscript in 2018. Congrats Blake (1st author) and rest of the team.
Farewell and good luck to Dr. Ongun Ozcelik and Dr. Nishant Garg. Ongun is at UCSD as a postdoc working with Prof. Paesani. Nishant is an Assistant Prof. at UIUC in the Civil and Environmental Engineering department.
