Application of the Static and Dynamic Models in Predicting the Future Strength of Portland Cements

The present study aims to analyze static and dynamic models predicting the future typical compressive strength of Portland cements. Both categories of models are based on physical and chemical characteristics and on the early strength of the cement types studied. The models performance was investigated and the superiority of the dynamic models was proved based on different criteria. Additionally the dynamic models offer the possibility to the industrial quality control to evaluate the reactivity of cement compounds in daily basis and to take the corresponding preventive and corrective actions. The implementation of these methods in the daily quality control is an essential factor of quality improvement by maintaining a low variance of typical strength.
