Reviewer 2 Report

For this study, we prepared high-belite-sulfoaluminate cement (HBSC) clinker containing brownmillerite. Thermal analysis, petrographic analysis and quantitative X-ray diffraction (QXRD) were used to determine the effect of brownmillerite on the mechanical performance of clinker sintering, clinker mineral and HBSC.

In this study, there are no special problems with the experimental design or material selection. However, the originality of this study is questionable. This is because this thesis is only basic data that can be used in the manufacture of cement clinker.

In order to raise the scientific level of this study, more experimental volume and deeper scientific inquiry are required. I do not think this paper will be of great interest to readers. This is because most of the predictions of the experimental results are possible.

The introductory part of this thesis does not know what the originality of this thesis is. And the development of the logic is not natural.

In terms of experimental design and content analysis, the overall content is simple and does not seem to contribute significantly to the cement field. Also, the conclusion part is really weakly written.

Therefore, I do not want this paper to be published in this journal.
