Microstructure and properties of Portland cement - Part 2: Prediction and sensitivity analysis

The first part of the paper dealt with the Evaluation of the Prediction Models [1]. In this paper, a sensitivity analysis by predictions from simulated variation of single x-variables and latent variables has been performed. Special attention has been paid to the influence of water sprayed into the first and the second chamber of the cement mill, respectively, on the dehydration of gypsum and prehydration and, further, on the cement properties. The influence of grinding aid on the fineness of limestone filler was also examined.
