Reviewer 2 Report
This paper is well written. The presentation is clear and the data is well presented. The only thing need to be concerned is the scientific soundness of the research study. If the author can provide the way of using these findings concerning the properties or applications of the high strength concrete, then it could be better.

Reviewer 3 Report
This is a reasonably scholarly experimental study of the load-induced temperature of ultra-high performance concrete (UHPC) under fatigue loading. The results reported here would provide useful information for engineering applications. In its current form I have some observations and comments:
It is observed that the temperature of UHPC increases when exposed to fatigue loading. Thermal stress (due to temperature gradient) is believed to influence fatigue strength. This is an interesting finding. However, no such results have been reported for normal strength concrete. So, an explanation should be given for this difference. Abstract, Line 20: “The thesis is that warming up, ……” The meaning of this sentence is vague. Page 2, Section 2: the details of the preparation of UHPC should be reported. For example, the type and gradation of fine aggregate and coarse aggregate. The mix composition of UHPC. Do you use any superplasticizer and pozzolanic materials for making UHPC? Page 8, Fig. 6: which mix was tested to produce data for this figure? Page 11, Line 311: what authors mean about velocity? Page 13, Line 385: what authors mean about Chapter 3?

Reviewer 4 Report
Dear Authors,
I find the research topic worthy for publishing, the experiment was well designed, conducted thoroughly and both parts of the manuscript is well detailed. Therefore, I recommend the acceptance of your paper, after minor revision. For the camera-ready paper, I advise to improve in the following in your paper:
Correct the formatting and spacing between the figures, tables and text. E.g. line 71 and line 243. Correct text caption under Figure 4. (line 137-139) Consider rearranging Figure 5. into different positions. Figures generally could be improved in their image quality, especially texts in the figures. Percentage should be written right after the number without spacing, e.g. 65%.For further studies, It may be interesting to study UHPC's thermal properties, such as thermal conductivity, thermal diffusivity and their moisture content and their relations to the heating rate, too.

Reviewer 5 Report
The authors have presented a research paper which investigates "Experimental investigations on the temperature increase of ultra-high performance concrete under fatigue loading".This article is well written and could be a valuable contribution to the construction sector. Overall, this manuscript is an excellent one and could be published once the following items are addressed.
line 39 : This has already been investigated by [1–9]. it can be written investigated by various researchers[1-9].
introduction part can be extended.
Summary, Conclusion, and Outlook
it can be separate and make summary and outlook one point
and conclusion part another point
