How do you bring innovation to a substance that has been used for over 2500 years? By going back to the basics. For a substance that is more widely used than any material on Earth, surprisingly little is known about concrete on a molecular level. The CSHub's paradigm-shifting models will allow scientists to understand the complex properties of concrete on the atom-scale, providing a mechanism to understand new structures and formulas from the ground up. This understanding will allow the CSHub to better understand how to reduce the energy required to manufacture cement -- a vital contribution considering concrete makes up 5% of human greenhouse gas emissions.
