ENHANCED THERMODYNAMICS ANALYSIS COUPLED WITH TEMPERATURE-DEPENDENT MICROSTRUCTURES OF CEMENT HYDRATES

Abstract

Systematic sensitivity analyses were carried out in order to investigate the effect of temperature history on hydration, micro-pore structure development, and moisture profile in concrete. In the numerical modeling, temperature-dependent intrinsic porosity of hydrates and available space for hydrate precipitation were taken into account. The proposed method can well predict hydration processes for different mix proportions under various temperature conditions.
