Experimental Study on the Corrosion of Fulvic Acid to Cement-Soil and Its Microstructures in the Peat Soil Environment

Round 1

Reviewer 1 Report

Appreciating your effort to complete this work.

The aim of the work is missing.

Conclusion section is mainly a repeated summary for the data more than to be a conclusion.

Many comments need answers. Please find commented manuscript in the attachment.

Reviewer 2 Report

Reviewer #2: The research in this paper is not a new topic; the same authors have already published another article on the same topic, https://doi.org/10.1155/2022/1437733. Therefore, I cannot recommend the manuscript for consideration and possible publication. In addition, the authors did not give a clear purpose and research methodology for the study. The authors should make substantial revisions, starting with making clear to the reader the purpose and methodology of this study, what are the control groups and variables? What did we get with this variable

 

-L12, Is the fulvic acid (FA) solution a simulated peat soil environment’s (PSE) corrosion?

-L19, “When the cement-soil is in the PSE,” Is it a PSE or a FA solution?

-L19-23 and L23-29, The descriptions in these two paragraphs seem to be repetitive.

-The description of the results in the abstract is too cumbersome. Most of these results are predictable, which is not new knowledge.

-The abstract needs to clarify the purpose of this study. Are the authors studying the corrosion resistance of cement-soil or the degree of corrosion of cement-soil in different environments?

-L95, “there are few studies combining the two” Are “two” is SEM or MIP?

-The advantages and significance of this study are not clear in the introduction section.

-What's the remaining 60%?

-What is the mixing ratio of the different color samples in Figure 3? What were the materials added?

-Indicate in the graph the name of the sample and the curing time

-Why is there no SEM graph for WWTL

- The deionized water curing in Figure 4a seems like a longer time curing graph.

-How the authors know it is "hexagonal Ca(OH)2" without performing EDS (EDAX) "microstructure.

-Figure 4(b) "SERL"

-What is the role of humic acid (HA)?

-“some of the hydration products of fibrous and flocculent cement are consumed by HA,” humic acid (HA) is detrimental to the structural stability of cement-soils.

-The size of the aperture represented by the different colors in Figure 8 should be given.

 

- Is the variable in this study simply the difference in maintenance methods (deionized water and FA solution)? This is the question that still puzzles me when I read this manuscript in line 340.

Reviewer 3 Report

Dear Author,

Paper gives an insight for microstructure of cement-soil in the peat soil environment, (PCAS), and unconfined compressive strength (UCS) test were carried out which gives the microstructure changes in cement-soil under the corrosion of peat soil environment (PSE). Kindly see the English grammar and sentence and modify it. See the references style and format and correct it. and resubmit the paper for final approval.

English sentence must be corrected with proper grammar and rewrite the sentence again.

Round 2

Reviewer 1 Report

Many thanks for your interest and replay
But
- Still the aim of work is confidently clear.
-The language still more revision
- Still the conclusion section too long .Please I made a summary for this section hoping it will help you (attached down below)
