(1)审稿人意见：
The paper brings some minor novelties on the binder production for refractory castables, but it is very unlikely that the suggestion proposed will be used on an industrial basis, as the cost/benefit ratio is not favorable.
该论文对耐火浇注料的粘结剂生产带来了一些小创新，但所提出的建议不太可能在工业基础上使用，因为成本/效益比并不理想。
Response to reviewers:
对审稿人的回应：
For this new type of cement, some calcium aluminate cement manufacturers have been interested in it and began to communicate with us. The cost/benefit ratio of CNTs/CAC can be reduced by using industrial raw materials and complete production process. Although we recognize that CNTs/CAC still has some difficulties in industrial production, it is credible and feasible in synthesis and sintering technology.
对于这种新型水泥，一些铝酸钙水泥厂家已经产生了兴趣，并开始与我们交流。通过使用工业原材料和完整的生产工艺，可以降低CNTs/CAC的成本效益比。尽管我们认识到CNTs/CAC在工业化生产上还存在一些困难，但其合成和烧结技术是可信且可行的。

(4)审稿人意见：
On page 14 the authors need to also consider the CA6 phase formation. Actually, it will be much better to add the X-ray diffraction profile after firing the castables at high temperatures.
在第 14 页，作者还需要考虑 CA 6 相的形成。实际上，在浇注料高温烧成后添加X射线衍射图会更好。
Response to reviewers:
对审稿人的回应：
On page 14, the XRD pattern of castable matrix has been added (Fig. 11), and the formation of ceramic phases, including mullite and CA6, has been proved, and the influences of ceramic phases on the properties of castable have been considered, which were marked in red.
第14页增加了浇注料基体的XRD图谱（图11），证明了莫来石和CA 6 等陶瓷相的形成，以及陶瓷相对浇注料基体的影响。已考虑浇注料的性能，用红色标记。
(5) Reviewer's comments:
(5)审稿人意见：
On page 16 the emphasis of toughening effect on the thermal shock results are too strong and very unlikely, as usually these formed whiskers are flexible and have no effect on the crack bridging or crack deflection effect. The better result for the thermal shock might only be due to the higher content of carbon left after firing, as it increases the thermal conductivity.
第 16 页对热冲击结果的增韧效应的强调过于强烈且不太可能，因为通常这些形成的晶须是柔性的并且对裂纹桥接或裂纹偏转效应没有影响。热冲击的更好结果可能只是由于烧制后留下的碳含量较高，因为它增加了导热性。
Response to reviewers:
对审稿人的回应：
On page 16, The effect of thermal conductivity on the thermal shock resistance of castables is regarded as the main factor and revised.
第16页将导热系数对浇注料抗热震性能的影响作为主要因素并进行了修订。

(1)审稿人意见：
Unnecessary focus has been given to the cobweb pattern of CNT as if it generates many advantageous properties in the refractory. It would be improper to conclude too much based on microscopy , specially in TEM, since it provides very local information. In a CAC composite, where the CNT% is aprox 23% , there must be some sort of aggregation Focussing on the CNT morphology is unnecesasary and often misleading if it is correlated to enhancement of properties.
人们对碳纳米管的蛛网图案给予了不必要的关注，就好像它在耐火材料中产生了许多有利的性能。根据显微镜（特别是 TEM）得出太多结论是不合适的，因为它提供了非常局部的信息。在 CAC 复合材料中，CNT% 约为 23%，必然存在某种聚集。如果关注 CNT 形态与性能增强相关，那么关注 CNT 形态是不必要的，而且常常会产生误导。
Response to reviewers:
对审稿人的回应：
In the TEM results, redundant detailed description and analysis of CNTs morphology has been deleted and revised, which were marked in red. Besides, the misleading analysis in the thermal shock performance has been revised.

Mechanical strength, oxidation resistance etc properties are strongly correlated with apparent porosity also. The authors did not consider it.
机械强度、抗氧化性等性能也与表观孔隙率密切相关。作者没有考虑这一点。

The mechanical data like CCS, MOR are presented without statistical information, hence are less reliable.

(4)审稿人意见：
The three types of CAC-carbon composites need to be clearly described in a single place mentioning the Carbon content. It is mentioned in a scattered way.
三种类型的 CAC-碳复合材料需要在一个地方清楚地描述，并提及碳含量。是以零散的方式提到的。

(5)审稿人意见：
The cross section after oxidation indicates that these materials are significantly heterogenous in nature. When heterogeneity is clearly observed in low magneiifaction, how authors conclude on nature of carbon from TEM images.
氧化后的横截面表明这些材料本质上具有显着的异质性。当在低放大倍率下清楚地观察到异质性时，作者如何从 TEM 图像中得出碳的性质的结论。
Response to reviewers:
对审稿人的回应：
For castables, the main properties of carbon matters are the oxidation resistance and dispersion. The oxidation resistance of carbon is related to the graphitization degree, which has been proved by Raman analysis. The dispersion of carbon in castables is related to the water wettability of cement, which has been proved by water contact angles and carbon floating ratios. It should be emphasized that the microstructure of cobweb-like carbon and calcium aluminate particles also determines the wettability and oxidation resistance of cement. Compared with cobweb-like carbon, flake pyrolytic carbon has poor binding with calcium aluminate particles, so it is easy to oxidize and float at mechanical mixing.
对于浇注料来说，碳质的主要性能是抗氧化性和分散性。碳的抗氧化性与石墨化程度有关，这一点已被拉曼分析证明。碳在浇注料中的分散情况与水泥的水润湿性有关，这已通过水接触角和碳漂浮率得到证明。需要强调的是，蛛网状碳和铝酸钙颗粒的微观结构也决定了水泥的润湿性和抗氧化性。与蛛网状碳相比，片状热解碳与铝酸钙颗粒的结合力较差，因此在机械搅拌时容易氧化、上浮。

Why it is relevant to present the TEM image of Fe catalyst particle?
为什么与呈现 Fe 催化剂颗粒的 TEM 图像相关？
Response to reviewers:
对审稿人的回应：
SEM images of Fe particle showed that it was attached to calcium aluminate particles, and no evidence of catalyst encapsulation was found in carbon nanotube tip. Therefore, Fe particle may be formed by melting of the catalyst. This shows that carbon nanotubes follow a base-growth mechanism and grow between calcium aluminate particles.
Fe颗粒的SEM图像显示它附着在铝酸钙颗粒上，并且在碳纳米管尖端没有发现催化剂封装的证据。因此，Fe颗粒可以通过催化剂的熔化而形成。这表明碳纳米管遵循碱生长机制并在铝酸钙颗粒之间生长。
