An Adaptive Homogenization Scheme for Modeling the Effective Elastic Properties of Early Age Concrete

Abstract

This study aims to develop a simple yet accurate adaptive homogenization approach for modeling the effective elastic properties of concrete for the whole hydration range from early age to hardened state. Considering available data from a similar microstructure, the method accurately accounts for the impact of cement hydration degree on the effective elastic properties of the heterogeneous concrete mixture. The simulation results have been validated against experimental data and demonstrate exceptional agreement. Also, we have detailly discussed the role of water and the effect of the destructive and non-destructive measurement methods. The model’s simplicity and accuracy make it highly applicable in practical engineering scenarios.
