The focus in this study is on the effect of high energy milling on tricalcium silicate, the main constituent of ordinary Portland cement. Changes in the performance, e.g. hydration heat release, due to milling in a planetary ball mill (Pulverisette 5, Fritsch, Germany) were observed. For comparison, carefully milled tricalcium silicate was produced with the almost exactly same particle size distribution by mortar grinding (KM100, Retsch, Germany). In summary, the results indicate that due to high energy milling the performance of tricalcium silicate can be improved significantly: the hydration heat release is much higher at early hydration time. Also the peak and duration of the dormant period was shifted due to high energy milling. The X-ray diffraction analysis shows that the structure of the material changed in such a way that the amorphous content increases. Further results of surface analysis are shown in this study.
