Multiscale Model for Temperature Distribution in Hydrating Concretee
摘要
Temperature rise in hydrating concrete presents a formidable problem that may lead to significant acceleration of hydration kinetics, early-age cracking, and decreased durability. Multiscale formulation is proposed, coupling a cement hydration model on the microscale with the finite element method (FEM) heat conduction problem on the macroscale. Particularly, discrete hydration model predicts heat evolution controlled by macroscale temperature, while the FEM satisfies heat balance equation during thermal conduction. Two- and three-dimensional validations show a reasonable temperature conformity with an access to the local quantities, such as a degree of hydration.
