dissolution-induced creep. Finally, simulation results show that our approach can predict
various mesoscale mechanisms of HP formation and clarify how these affect the hydration
rate. Overall, this is a first step in developing nanoscale simulations that can contribute to the
challenge of understanding and controlling the formation, setting, and chemo-mechanical
degradation of concrete.
