Round 1

Reviewer 1 Report

In this paper, the mechanical and durability properties of CCD optimized fibre reinforced self compacting concrete are studied. The research has certain originality. There is some interest among the researchers involved. But there are some contents should be revised.

1. PCB, CCD, FRSCC and so on, the abbreviation should be explained at the first appearance in the article, it is better in the abstract.

2. What is the mean of the E-waste? And why do you choose it as the replacement?

3. In the abstract, it is concluded that optimum percentages of E-Waste, Recycled aggregate and synthetic fibres are 9.90%, 51.35% and 0.503% respectively. What is the mean of the optimum percentages? At this percentage, the workability or the compression or bending performance is the best?

The Recycled aggregate should be changed to recycled aggregate.

4. Self-Compacting Concrete or self compacting concrete? It should be consistent in the whole manuscript. Which of the capital letter or the lowercase is right?

5. How about the workability of the SCC and FRSCC? Photos of the materials and specimens of the test should be added in the manuscript.

6. The Table 9 and Figure 3 show the same content. They are repeated.

7. The curves in Figure 4 should be analyzed with mechanism in depth.

8. The analysis of the Figure 6 is absent.

9. The style of the references are disordered and there are no newest reference in recent three years.

Round 2

Reviewer 2 Report

N/A

Author Response

Reviewer: 2

  1. Is the research design appropriate? – Can be improved

Response: “The aim of this study is to find a way to combine the benefits of fibre-reinforced concrete and self-compacting concrete without sacrificing the performance of either. To achieve this, the researchers propose adding polypropylene fibres to self-compacting concrete mixes, which they believe will improve the strength of the material without hindering its ability to flow through complex, congested reinforcement areas. This approach could have significant benefits for the construction industry”

The research significance and research design appropriate has been added in Line 119-127.

  1. There is no further comments and suggestion in the “Comments and Suggestions for Authors”
