Abstract

A computer-based numerical model is presented in which hydration and microstructural development in Portland cement-based materials can be simulated. The proposed model enables the prediction of hydration curves as a function of particle size distribution and the chemical composition of the cement, the water to cement ratio, and the actual curing temperature. The mutual relationship between developing the microstructure and its effect on the hydration process is modeled explicitly. Finally, predictive accuracy of the proposed model is assessed with 50 different calorimeter tests who have different cement composition, water to cement ratio, particle size distribution, and curing temperature. As a results, averaged ratio of predicted value to experimental value of 0.994 and a predictive standard error of 5.9% are obtained, and these values can be concluded as an indication of good accuracy of prediction.
