Properties and Performance of Tricalcium Silicate Milled in a Planetary Ball Mill
Acta Physica Polonica A, 2014 The focus in this study is on the e ect 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
