The Influence of Animal Glue as an Additive on the Properties of Lime Architectural Grouts
Round 1
Reviewer 1 Report
The author has made a good attempt to understand the "influence of animal glue as an additive on the properties of lime architectural grouts". However, a few comments are mentioned below:
1. In the abstract methodology (which method they have applied) and results are missing.
2. How Organic additives from plant and animal extracts are extracted? The details are missing
3. Line 64 & 65, I am surprised how this statement is valid and no chemical reactions are discussed.
4. Research gap is missing.
5. Objective is not well defined.
6. Study area details are missing.
7. Samples collection and conducting experiments details and photographs are missing
8. Author should clarify which guidlelines they have followed
9. Figure 1. ATR- FTIR spectra of pure fish glue discussion should be more effective.
10. How you decided the Binder/filler mass ratio and Limestone filler F40 : F15 : F5 mass ratio
11. Conclusion should be more effective in point wise
12. Signicifance of research output is missing.

Author Response
We thank Reviewer 1 for the constructive comments on our manuscript. We have gone through your comments carefully and tried our best to address them one by one. We hope the manuscript has been improved accordingly.
- In the abstract methodology (which method they have applied) and results are missing.
Author response: We have revised the abstract and included methodology and results of the study.
- How Organic additives from plant and animal extracts are extracted? The details are missing
Author response: We have included the description of the animal (fish) glue production in the text [p. 4, line 129-131].
- Line 64 & 65, I am surprised how this statement is valid and no chemical reactions are discussed.
Author response: In the text we explain the chemical reaction (p. 2, line 72-74).
- Research gap is missing.
Author response: Thank you for your comment. In the research work, we want to find out whether animal glue in lime grout effectively fills and stabilizes detached plaster layers, while improving its resistance to environmental effects.
5.Objective is not well defined.
Author response: Thank you for your reminder. We revised the objectives of the study [p. 2, lines 82-91]
- Study area details are missing.
Author response: Thank you for your reminder. For better understanding the study area we provide the flow diagram of research progress [p. 5, line 163]
- Samples collection and conducting experiments details and photographs are missing
Author response: Thank you for your reminder. We provide photographs to support the description of the test methods.
- Author should clarify which guidelines they have followed
Author response: Thank you for your reminder. As we wrote in the manuscript, we followed guidelines proposed by Biçer-Şimşir and Rainer [8] or Padovnik and Bosiljkov [2] [p.5, lines 174-175].
- Figure 1. ATR- FTIR spectra of pure fish glue discussion should be more effective.
Author response: Thank you for your reminder. We revised the discussion about ATR-FTIR spectra of pure glue [p. 4, lines 138-143].
- How you decided the Binder/filler mass ratio and Limestone filler F40 : F15 : F5 mass ratio
Author response: Thank you for the question. The proposed ratio of the F40 and F5 fillers was chosen on the basis of preliminary studies where the stability and injectability of the grout was the most important factor.
The binder/filler mass ratio was also chosen based on preliminary research, where we found that grouts with the binder/filler mass ratio 0.28 showed the best overall behaviour in the fresh and hardened state and provide effective stabilization of detached plaster layers.
- Conclusion should be more effective in point wise
Author response: Thank you for the question. We revised the conclusion section [p.16, lines 464-510].
- Signicifance of research output is missing.
Author response: Thank you for the question. We included significant research outputs in the conclusion [p. 16, lines 511-514].
Reviewer 2 Report
Authors studied the influence of animal glue as an additive on the properties of lime architectural grouts. The manuscript can be improved based on the following comments:
1. Please add SEM pictures of the fillers if applicable.
2. “A polycarboxylate ether-based superplasticizer (PCE) with a relative density of 1.05 g/cm3 and a pH of 5.5 ± 1.0 was used as a highly effective water-reducing agent to achieve adequate viscosity and injectability of all tested grouts in the fresh state.” And Table 4. Composition of grout mixtures: PCE (5 %): by the weight of the cement or the mixture, please explain it in Table 4 or the text.
3. Please add the test photos, if applicable.
4. Please compare this “ Furthermore, the lower W/B ratio does not improve the adhesion strength, when we compare the normally aged reference specimens LS and LF with LS-G2 and LF-G2. For the 2-mm air pocket, the reference grouts (LS and LF) and grouts LS-G2 and LF-G2 with low W/B ratio reach the values of 0.10 MPa and 0.15 MPa, respectively. The adhesion strengths for the 5-mm air pockets injected with grouts LS-G2 and LF-G2 decrease compared to the reference grouts” with the existing literature.
Or it looks more like a technical report in this manner.
5. Please add a flow chart in order to better understanding of the study.
6. Please check this part in the conclusion: “The addition of animal glue as an additive does not influence the fresh properties of grouts.” How about the fluidity test results that was given in related Tables ?

Reviewer 3 Report
This paper describes an experimental investigation to study the influence of animals and the role of filler particle size in lime grout by testing the workability properties and mechanical strength of 90 and 365-day-old specimens.
The article is very well presented and the authors covered a very long period of time for testing samples 365 days.
The research design and methods are clear and the conclusions are very sufficient.
The only thing I would recommend is that the author rewrite the abstract as it is not fully describing the contents of the paper.
English language is very well written

Response: Thank you very much. We have rewritten the abstract.
Reviewer 4 Report
The article contains the results of quite extensive experiments and is certainly of interest.
In Table 7, it is necessary to clarify the location of failure before the accelerated aging of grouts injected into 5-mm air pocket for the LS mixture. According to the table, the destruction takes more than 100%.
