Research on the Detection and Measurement of Roughness of Dam Concrete Layers Using 3D Laser Scanning Technology
Round 1
Reviewer 1 Report
Page 2(55-58) “Generally speaking, the method based on "surface" sampling, because the combined surface information collected and used for calculation is more, compared with the method of "line" sampling, it has higher precision, and the detection result of multiple repeated sampling The fluctuation is smaller [8].” Long sentence split into two and check correctness and capitalization.
Table 1. Mix proportion of concrete (KG/M 3). Unit should be kg/m3
Page 4 (118) “According to the mix proportion in Table 1 pouring A-layer concrete specimens, standard curing after three days with high-pressure water gun processing.” Check grammar.
PAGE 4-5 (120) “After standard curing for 3 days, the poured concrete A-layer specimens were divided into three groups. One group was used as a control experiment without treatment, one group selected 15MPa scouring strength, and the other group selected 35MPa scouring strength.” Check grammar.
In Table 2 use significance number and write up to three decimal places.
Figure 6 is not clear what has been plotted on x-axis and y-axis?
Why MR-N has less strength at 28 days as compared to 14 days?
The fitting curve of the correlation between the splitting strength and the filling volume has lesser R2. Please explain reason.
Where is practical demonstration of the method? Without practical in field data, this is incomplete study.
Page 17 (411) “l. In fact, as long as the light conditions are good, 3D laser scanning technology can scan the joint surface to be inspected at any angle. 2) This method is a non-contact non-destructive testing method.” This required a demonstration of the effectiveness of technique in field.

Reviewer 3 Report
The abstract is very long, however, it does not contain results or percentages obtained from the researchز So you need to rewrite it to be more useful to the reader. The same applies to the conclusions section

Round 2
Reviewer 1 Report
The manuscript is now in a suitable form and consider for publication, however, the response of the Authors should also be portrayed in the main manuscript in an appropriate manner.
