The authors regret that the SEM image of GO (Fig. 1) should be replaced by a more representative one, which is provided by the material supplier, as given below. The workability measurement (Fig. 2) was plotted incorrect and should be revised by the following. Consequently, the sentence in Abstract should read as follows: The mini-slump diameter was reduced by 27% with the incorporation of 0.03% by weight GO in cement paste. The sentence in Section 4.1 should read as follows: However, when 0.03% by weight GO was added, the mini-slump diameter showed a sudden decrease to a level that was about 27% lower than that of the plain cement paste C. The Acknowledgement should read: The authors are grateful for the financial support of the Australian Research Council in conducting this study. Thanks also go to Mr. Samuel Chuah and Mr. Hongsen He for their great support in materials testing during their stay at the Monash University. The authors would like to apologise for any inconvenience caused.
