Abstract
The authors presented a computational system that can predict long-term degradation of cement hydrate due to calcium leaching. For simulating leaching of calcium ion, equilibrium of calcium ion in solid and liquid and ion transport were formulated on the basis of thermodynamics theory. The time-dependent material properties of cement hydrate were evaluated considering the inter-relationship of hydration, pore-structure development and moisture transport based upon fundamental physical material models. The proposed model can reasonably predict the calcium leaching in concrete.
