Reviewer 2 Report
No density of cement and aggregate has been provided. Usualal density of OPC and granite is 3.1kg/dm3 and 2.61-2.65 kg/dm3, respectively. Then
The sum of absolute volumes of all ingredients is less than 1000 dm3,
Please explain or correct the existing situation.
The article does not give any data on the properties of concrete.
Please explain why an extremely high amount of superplasticizer was used. The content is much higher than the maximum recommended. No chemical composition of the admixture is given.
Polymer admixtures should be used for SCCs.
The sample size (25x20mm) is too small when using 10mm aggregate. Test results may not be reliable.

Reviewer 3 Report
This paper presents the experimental study on the creep of cement matrix modified with nanoparticles. Although the novelty of the paper is limited, the test results are well presented in the paper. Several detailed comments need to be addressed by the authors.
- The indentation method is a standard test method, which is not necessary to be introduced in the background literature review. Instead, studies on the creep of high performance concrete should be reviewed and presented in the paper.
- Why 4% of nanoparticle is selected in the mix design?
- Table 3, table number is wrong
- Please discuss in detail the differences between the presented test and the test reported in Ref [18]. Did you just repeat the test? and what cause the different findings between the present result and the others' results?
