Reviewer 2 Report
The authors used glass waste into concrete filled steel tubular columns. The paper is generally good but it needs improvement. Followings should be carried out before acceptance:
The abstract should contain important results of the study.
Recent studies of using waste glass in conrete were omitted by the authors. The following studies should be included into introduction: influence of replacing cement with waste glass on mechanical properties of concrete; concrete containing waste glass as an environmentally friendly aggregate: a review on fresh and mechanical characteristics; mechanical behavior of crushed waste glass as replacement of aggregates
The slump value is very high_ Why?
How this recycled materials for this study is obtained?
Add sieve analysis results in Figure.
What is chemical properties of cement
Novelty is not clear. Very same studies are already exists. What is the difference?
The reason for selecting design mixture should be added.
Compare your results with existing studies
What is the initail contact area for specimens? Steel tube or concrete?
The importance of recycling materials to overcome enviermental prbolem should be added to introduction using: investigation of the physical-mechanical properties and durability of high-strength concrete with recycled pet as a partial replacement for fine aggregates; effects of waste powder, fine and coarse marble agregates on concrete compressive strength; se of recycled coal bottom ash in reinforced concrete beams as replacement for aggregate; ;flexural behavior of reinforced concrete beams using waste marble powder towards application of sustainable concrete
Why the spcimens did not fail?
Add some summary for conclucision
Add recent studies on this subject to introduction. There are many studies on the introduction for this topic.
Conclusion should be improved. The recommendation consdiering all test should be given for engineers.

Reviewer 3 Report
The authors have submitted a well prepared paper on the interesting topic of the experimental study on mechanical properties of concrete containing waste glass and its application on concrete-filled steel tubular columns. The paper is clearly presented and provides interesting results. This study is valuable for the practical engineering. However, the following comments are provided to assist the authors to improve the paper:
1) The article's purpose should be clarified in detail, why this study could be beneficial, and a more in-depth conclusion in applications should be provided.
2) Why is the deformation control with a loading rate of 0.4 mm/min? The author should have references and explanations.
3) Table 3. Summary of the test results: Why is the peak load of specimen GCFST-30 (1297.3 kN) greater than specimen GCFST-20 (1260.2 kN)? Please explain.
4) Please define abbreviations in table format for clarity.
5) The description in Lines 64-66 (Concrete-filled steel tube (CFST)) can refer to the literature: doi.org/10.4028/www.scientific.net/MSF.860.121
6) Please propose some improvements and directions for future research.
7) Please use the correct MPDI journal format style.
Thank you for considering my opinion. I encourage the authors to keep on working to improve the revised manuscript.
