TLDR
In this article, the effects of graphene and graphene oxide on the hydration, microstructures and mechanical properties of cement paste were investigated by using reactive force field molecular dynamics (MD), revealing that functional hydroxyl groups in GO provide non-bridging oxygen (NBO) sites that accept hydrogen-bonds of interlayer water molecules in the calcium silicate hydrate (CSH).About:
