4. ConclusionsIn this study, lic model is used to simulate the hydration of limestone Portland cement. Results of microstructure properties from lic computer program are comprised with the available pervious experimental results and CEMHYD3D computer model of Degree of hydration [10,20]. The conclusions pertaining from these comparisons are briefed as follows:1. The flexibility of lic model enables the easy inclusion of more cement phases and hydration conditions in simulations. It is also useful for studying the microscopic phenomena for comparison with experiments. 2. The lic model has been modified to consider the influence of limestone substitutions. Both the chemical and fine filler effects of limestone on cement hydration have been addressed. The lic model provides good agreement with experimental results and CEMHYD3D model.3. Degree of hydration enhancement by using limestone cement due to both its physical and chemical effect.4. Replacement of 5–10% limestone is associated with acceleration effect of degree of hydration, while, limestone fills the pores between the cement particles due to the formation of carboaluminate phases.5. More researches are needed to refine the model for better prediction.
