Experimental Investigations on Temperature Generation and Release of Ultra-High Performance Concrete during Fatigue Tests

Round 1

Reviewer 1 Report

The manuscript was well written. The methodology was well described. The results were clearly presented and discussed. Congratulations to the authors for this great job.

However, more deeply elaboration on the significant of this research and the main contribution of the achieved results needs to be discussed in the introduction and conclusion parts.

Furthermore, the conclusions can be summarized with the bullet points to be more direct and clear.

Reviewer 2 Report

The manuscript describes the second part of an experimental test on heat development in UHPC under fatigue action. The article is interesting and focuses on a not well-explored aspect of UHPC material relevant for engineering practice. The paper is written in good English with minor mistakes (ex. In order to increase the state of knowledge on this phenomenon, it was been systematically investigated mainly for UHPC in an own research project to find the main influencing parameters.) and has a clear structure. The methods are clearly described and a deep analysis of obtained results has been performed.

I would suggest the following minor changes:

1) placing legends on temperature plots instead of below (it will make it much easier to analyze),

2) Adding a force-displacement curve or similar in Fig.2 to make it clear that fatigue heating is caused by mechanical loading.

Apart from that the paper is very well written and I do not see a need for another review round and therefore suggest accepting the paper believing that the Authors will consider my minor remarks.
