- Abstract
- Further details are reported for a previously developed mathematical model for the hydration of tricalcium silicate. The model is based on conceptual models for the different stages of hydration. Sub-models are given which consider the effects of the particle size, thickness of the barrier layer, and ratios of diffusivities through the hydrate layers. The model suggests that the barrier layer responsible for the induction period is most likely to form a finite time after the cement is mixed with water, rather than immediately. Model predictions were consistent with experimental data.
