Abstract
Concrete is a heterogeneous material, and the presence of aggregates leads to the uneven distributions of the internal temperature and hydration degree. From a mesoscopic point of view, the distribution characteristics of the temperature field and hydration degree inside concrete were accurately investigated for different aggregate gradations with a fixed aggregate volume fraction. 2-D and 3-D mesoscale models with polygon and polyhedral aggregates were constructed. Based on the hydration model, a chemo-thermal coupling model of concrete was established. The distribution characteristics of the temperature field and hydration degree of early-age concrete were simulated by using 2-D mesoscopic models of concrete combined with the chemo-thermal coupling effect, and the effects of the aggregate gradation, boundary conditions, aggregate shape and precooling measures on the concrete hydration process were analyzed.
