Round 1
Reviewer 1 Report
It is judged that this paper lacks objective data on the results.
The results of figures 1 to 4 represent the state of the experiment and the production status of the specimen accordingly. However, I don't know if this is really meaningful data for readers.
There is no clear data consistency between the theoretical diffusion coefficient and actual experimental results. I hope the explanation is based on objective data.
Author Response
Q1. It is judged that this paper lacks objective data on the results.
Answer: Thank you so much for your suggestions. All the results are based on research data and its listed in Table1 and Table 2. We added more description about the details of experiment in section 2.1, hoping it will be helpful to approve the objectivity of the research.
Q2. The results of figures 1 to 4 represent the state of the experiment and the production status of the specimen accordingly. However, I don't know if this is really meaningful data for readers.
Answer: Thank you very much for your suggestions. All the data are collected in the tables, the Figures 1-4 are listed to help readers to have a clearer understanding of the test process.
Q3. There is no clear data consistency between the theoretical diffusion coefficient and actual experimental results. I hope the explanation is based on objective data.
Answer: We really appreciate you suggestion. The difference between theoretical diffusion coefficient and actual experimental results is due to the coupling influence between gravel soil porosity and cement grout weight as its studied in the paper. We fully understand your concerns. All the data is based on the authentic experimental data. Hoping more details will prove the objectivity of the data. If more figures is needed, we can add it. For now it is because too much figures will let the paper confusing.
Reviewer 2 Report
The authors experimented with water/cement to observe the Morphologie and Penetration Grouting. The research is interesting, however the authors should make some modifications to the manuscript in order to be accepted for publication.
In experimental studies section. The authors should make a brief description of the apparatus and experiments performed
The author did not show water-cement ratio used, temperature, water conditions, particle size of gravel soil, etc. They have to explain clearly the experiment
Which is the volume of the box, and the volume in liters of water/cement used in the experiment
The author experimented with different porosity and different water-cement ratio but they do not provide any picture as evidence of the most significant results to observe the morphology of cement grout into the gravel soil
In results and conclusions there is so much text and the reader lose the interest. I recommend the author should be punctual and concise. In conclusions the authors must recommend which water-cement ratio and particle size of gravel should be used in the field by enterprises.

Q4. In experimental studies section. The authors should make a brief description of the apparatus and experiments performed.
Answer: Thank you very much for your professional comments and suggestions. We have added description of the details of the apparatus and experiments performed which can be found in the section 2.1.
Q5. The author did not show water-cement ratio used, temperature, water conditions, particle size of gravel soil, etc. They have to explain clearly the experiment.
Answer: Thank you very much for your comments. According to your suggestion, we added all the information needed in section 2.1. Q6. Which is the volume of the box, and the volume in liters of water/cement used in the experiment?
Answer: This comment was supplemented according to the reviewer's suggestions, as detailed in the part 2.1 of the revised manuscript，such as ' …an external dimension of 600 x 600 x 600 mm ' . And we added the type of cement too.
Q7. The author experimented with different porosity and different water-cement ratio but they do not provide any picture as evidence of the most significant results to observe the morphology of cement grout into the gravel soil.
Answer: We appreciate your professional advice on our paper. The morphology of cement grout into the gravel soil can be seen in Figure 3 and we thought it might be confusing if we add too much figures. But if it is needed, we can add more figure.
Q8. In results and conclusions there is so much text and the reader lose the interest. I recommend the author should be punctual and concise. In conclusions the authors must recommend which water-cement ratio and particle size of gravel should be used in the field by enterprises.
Answer: We appreciate your professional advice on our paper. We rewrite the conclusion part in order to make it cleaner and brief. As for the engineering practice, we also added suggestions too.

Reviewer 4 Report
Review on the manuscript “Influence of Coupling Effects between Gravel Soil Porosity and Cement Grout Weight on Diffusion Laws and Morphologies of Penetration Grouting” by Yang et al.
The work is interesting but still needs some improvement.
Experiment device and experiment scheme – The references 21 and 22 are not by Yang – please check the references
In addition, some details should be introduced regarding the experimental procedure, not just the reference, so that the reader has a better picture of the whole process.
The mineral composition of cement should be presented in the article.
Was the effect of hydration ignored?
Line 95 - The penetration diffusion progress of the cement grout in the gravel soil can be were divided into three stages. – Please correct the English
Figure 2 and 3 should be merged
Table 3 is unclear; the last two columns should be adjusted
Figure 6 – a better resolution figure should be included
There are plenty studies in this field so a more thorough discussion should be added, highlighting the findings of this research.
The conclusion should be rephrased and shortened.

Q11. Experiment device and experiment scheme – The references 21 and 22 are not by Yang – please check the references.
Answer: We appreciate your suggestions. After the examination of the manuscript, we found we linked to wrong number, and we corrected them as 22,23.
Q12. In addition, some details should be introduced regarding the experimental procedure, not just the reference, so that the reader has a better picture of the whole process.
Answer: Thank you so much for your suggestion. As you suggested, a brief introduction about the details will help readers understand the research better. So we added more details such as ‘The grouting experimental device consists of three parts: test chamber, pressure supply device and cement container. [22-23]. The test chamber is composed of steel brackets and Plexiglas plates with an external dimension of 600 x 600 x 600 mm…’.
Q13. The mineral composition of cement should be presented in the article.
Answer: We appreciate your suggestions. We listed the used cement in section 2.1 ‘The grouting material used was ordinary silicate cement of grade #32.5 produced by Kunming Cement Factory’.
