Full Title: Systematic Experimental Assessment of POFA Concrete Incorporating Waste Tire Rubber Aggregate.
The manuscript describes the Systematic Experimental Assessment of POFA Concrete Incorporating Waste Tire Rubber Aggregate. The manuscript needs a detailed editing. Some markings are made to just illustrate the extent of editing needed.
The authors need to consider the following comments
- Add more suitable keywords.
- The introduction section should be improved; more related papers must be discussed and critical improvement in this study must be clarified.
- Line number 68 – author should check - ……… enhance the acoustic and ductility properties in concrete. [23, 24], and also bring…..
- Figure 3 – not clear make clear.
- 2.3. Experimental program- section should be detailed.
- Please provides the references for all equations and formula.
- Figure 14: The XRD pattern of the (a) 100% OPC (b) 100% POFA and (c) 0% and 20% POFA of prepared concretes. Not clear make clear.
- SEM: how the energy of the accelerator beam used?
- 3.8 Scanning Electron Micrographs - section should be detailed.
- Conclusions: the authors need to improve with more specific results and conclusions.
- Several faults: are added or missing spaces between words: see manuscript file.
- And make all references in same format for volume number, page number and journal name.
So that I recommended this manuscript to major revision and for future process.

Reviewer 2 Report
The manuscript entitled “Systematic Experimental Assessment of POFA Concrete Incor-2 porating Waste Tire Rubber Aggregate” introduced interesting results. However, some comments below should be addressed:
- In the abstract, the goal of the paper sentences in lines 28-31 is so long.
- In the introduction, the last paragraph is also so long, and the contribution of this work is not clear in this paragraph.
- Sentences in lines 99-103 should be in the methodology.
- Figure 3 is presented in your previous work. please add the citation.
- Please add a diagram of how to link RSM to perform the experiments.
- In the RSM model figures in the counter figures (figures 8(c), 9(c), 10(b)) the y axis should be "curing period (day)".
- Figure 14 needs to improve in resolution.
