A multiphysics–multiscale model of Portland cement hydration predicting temporal evolution of microstructure and strength-relevant properties

Kunlun Li, Muyu Liu, Hua Li, Guitao Luo et autres

Portland cement strength is governed by hydration properties including heat flow, hydration degree, porosity, pore size distribution, portlandite content, ratio of calcium to silicon, and mean chain length. However, no existing model theoretically predicts all these parameters by considering the hydration time. …

A novel adsorption–complexation–rheology model for PCE effects in early‐age Portland cement hydration

Guitao Luo, Hua Li, Muyu Liu, Kunlun Li et autres

Abstract Superplasticizers play dual regulatory roles during early Portland cement hydration they retard hydration kinetics while enhancing paste fluidity. However, research gaps remain in quantitatively modeling the retardation behavior of superplasticizers and in establishing mechanistic linkages between the time‐dependent rheological effects in …

Hydration kinetics of Portland cement shifting from silicate to aluminate dominance based on multi-mineral reactions and interactions

Yang Liu, Muyu Liu, Hua Li, Guitao Luo et autres

A theoretical model for cement hydration was proposed to study multi-mineral reactive transport processes under various mineral compositions and determine the effect of multi-mineral reactions and interactions on cement hydration kinetics shifting from silicate to aluminate dominance. The reaction rates of each …

Role of ionic diffusion in heat flow and chemical shrinkage of tricalcium aluminate hydration subjected to thermo-chemo-electrical coupled fields

Yang Liu, Hua Li, Muyu Liu, Guitao Luo et autres

The role of ion diffusion in the heat flow and chemical shrinkage of tricalcium aluminate (C3A) hydration was investigated using the proposed multi-ionic reactive transport model for C3A hydration. Ion diffusion, dissolution, and precipitation reactions were coupled in the governing equation of …
