May 06, 2019 Cement hydrates are small, on the nanoscale scale, says Tingtao Zhou, a PhD student in the Department of Physics and the lead author of the paper. These are the building blocks of cement. During cement hydration, the cement hydrates nanograins aggregate with each other, forming a network that glues all constituents together.
