X-ray Diffraction of Alkali-Activated Materials with Cement By-Pass Dust
Round 1
Reviewer 1 Report
- Table1, you have here and there comma instead decimal dot.
- There is some mess with figure numbers. You have two figures 2 and three figures 3. Please correct.
- References mentioned in the text should be also corrected, they must be placed before dot at the end of sentence. Otherwise it looks like new sentence started with square bracket.
- XRD pictures are formatted in different way. Are they made in different devices or software? Please, make some remark in the text about that.
- There is needed some comments about LOI.
Utilisation of dust with high LOI is difficult because of carbon content and LOI value must be lower than 16%. For sure, in cement by-pass dust must be a lot of unburnt carbon from kiln fuels. However your dust has 21.9% DOI and XRD analyse did not detect the carbon. Why? - Table 4. i think that "recipe" is more appropriate word instead "reception". It is hard to estimate mixtures recipes when it given in g. More convinient would be given in mass%. However, only change in mixtures is activator mass. Why the rest of mixtures compounds masses are the same. How were chosen proportion in masses. Please insert some comments in the text.

We are thank you for the revision carried out, for valuable suggestions for improvement and additions to the text. The suggestions are appreciated and we have tried to incorporate them into the corrected text. We have marked the changes made in the text in red.
Comments for points
1. Thank you for the notice. We have made the correction directly in the text
2. We apologize for the confusing numbering of Figures. We have corrected the numbering of the Figures and moved some of tham tho diferent part of text.
3. Thank you for your attention, we have corrected the format.
4. Figure 4 is a schematic. The aim was to show the differences between the mixtures. Figures 1-3 are more detailed - we have modified the figures for better usability.
5. Regarding Loss on Ignition , the loss is due to sulfate and alkali decomposition (likely Sylvite decomposition) + limestone decomposition. The carbon content of the dusts is unlikely due to the sampling location and temperatures.
6. Thank you for your attention I have added the table and the text has also been added on line 103.
We hope that we have managed to complete everything and answer all the questions raised.

Thank you for the very detailed rewiew. We have tried to incorporate all your suggestions and comments, we hope we have succeeded.
We have divided the responses to the comments into Pages as they appear in the rewiew. The current page numbers may not match. Please also refer to the changes on specific lines in the text. All the changes made are marked in red in the text.
For a better understanding of the content of the figures concerning mechanical properties, we have moved and renumbered the figures. We have moved the figures to Chapter 2.6 where we have also added text on lines 103 and 113.

We have edited the title to not contain the abbreviation. In addition, other abbreviations have been added to the text.
We added a comma after Ostrava Poruba.
We have corrected the abstract according to your suggestion.
We have corrected the sentences on lines 28,35,38,41,50.
Comments - Page 2
We corrected the text on line 56.
Table 1 - we have added an explanation of the abbreviations FA and LOI.
Figure 1 - corrected the title and edited the figure to make it more obvious what the figure is.
We corrected the sentence on line 61 and added an explanation of the abbreviation.
Comments - Page3
Figure 2 - The results presented in this figure are part of our research and have not yet been published. I have tried to modify the figure to make it more readable and provide the information that is needed.
I have added an explanation of the figure on line 86.
Comments - Page 4
The chemical and phase composition of CBPD is taken from the report "Deliverable D1.1 Results from raw materials analyses" within the GeoDust project. The evaluation of the measurements was done in software HighScore.
We have corrected the title 2.4.
We corrected the sentence on line97, 107-119.
We corrected the title of Table 4 , the title was added based on the second opponent's request .
We have corrected the text on line129.
Comments - Page 5
We corrected text on line 129 - 131 - correct water content.
We corrected text on line 140.
Comments - Page 6
The numbering of images has been corrected.
Comments - Page 7
We have corrected the first line in the discussion section.
We have completed the text on lines 154-158 and added an explanation of the term: sodium/potassium water glass .
I have completed and corrected the sentences on lines 164-168,172-174, 178-182,198-200.
Figures originally located on page 7 have been moved to subchapter 2.6.
We have removed the reference 33.
I have tried to answer all the questions and make all the required corrections and adjustments. We hope that now the article is better and more in line with the standard of the journal.
Thank you again for your help and valuable comments
Round 2
Reviewer 1 Report
The newest version is much better. However, there are some editing mistakes. ie. P.3 L.86 "ignition". I feel also that the LOI question is not resolved completely, but the overall impression of the paper is fulfilled.

Thank you for your patience and help with improving the text.
We have tried to describe what we think the LOI ( high percentage) is caused by. We are aware that the answer is not completely accurate and unambiguous. It is a suggestion for us in future researches what will need more attention and focus.
We've made the suggested correction in text.
Than you for review.
Reviewer 2 Report
After the revision, this paper is significantly improved, and, in my opinion, it can be published in the present state.
