Factors affecting properties of polymer grouted sands

civileng-2762223-review

1. It is mentioned that the elasticity modulus of fine sands pattern is 75-480 MPa. Are you sure the value is correct?

2. Please add discussion section. There should be a review on what has been studied before on this topic. Discussions should also include some comparison with some existing works done elsewhere. Have a similar method and study performed before by other researchers? What is your major contribution to the existing studies? You need to discuss if your work is new and innovative, and what advancement you made in tunnelling technology. Again, you need to compare your work against the existing work done worldwide, with references. You basically need to follow the logic to explain: why you want to study this problem, why you select this method, what have other people done already, what you have obtained from the test and analysis, what is the comparison with other people and other methods, what are the advantages, and how they will change the polymer grouted sands.

3. Please explain what specific help or guidance your research has on the existing engineering application?

4. The conclusion is too scattered. Maybe the author should concentrate on a scientific problem and delve into it deeply.

Reviewer 2 Report

Comments and Suggestions for Authors

The article studies the influence of epoxy resin grouts on the physical and mechanical properties of sands. The article is clearly written and relevant. Figures with setups help to better understand how the tests were done. The article has the following comments and suggestions:

-Line 129: What was the load?

- From Figures 8 and 9 it can be seen that the strength values reached a constant line after 90 days. For comparison, provide a graph of the results obtained after 90 days when testing compressive strength depending on the distance from the injection point for sand S5 (Figure 7). It is best to give such comparison graphs for sand S3.

-Place graphs and tables after the link that points to them. It is not convenient to scroll the text down and up every time.

-Please indicate in your conclusions which composition turned out to be the best.
