RETRACTED ARTICLE: The effects of ZnO₂ nanoparticles on split tensile strength of self-compacting concrete

Abstract

We the Editor and Publisher of Journal of Experimental Nanoscience retract the following three articles:

1.	Nazari, Ali, and Shadi Riahi. “The effects of ZnO2 nanoparticles on split tensile strength of self-compacting concrete.” Journal of Experimental Nanoscience 7.5 (2012): 491-512, https://www.tandfonline.com/doi/full/10.1080/17458080.2010.524669
2.	Nazari, Ali, and Shadi Riahi. “The effects of SnO2 nanoparticles on physical and mechanical properties of high-strength self-compacting concrete.” Journal of Experimental Nanoscience 7.5 (2012): 559-577, https://www.tandfonline.com/doi/full/10.1080/17458080.2010.543991
3.	Nazari, Ali, and Shadi Riahi. “The effects of ZrO2 nanoparticles on strength assessments and water permeability of concrete in different curing media.” Journal of Experimental Nanoscience 8.4 (2013): 413-433, https://www.tandfonline.com/doi/full/10.1080/17458080.2011.586369

Since publication it has come to our attention that these articles duplicate significant parts of other papers published elsewhere and that these were not referenced within these articles (listed above). Following COPE guidelines, Taylor & Francis has tried numerous times to contact the authors as well as their affiliated institutes with a request for clarification, however, we failed to receive a response.

As we have been able to verify that unreferenced content has been duplicated, we have decided to retract these articles. We apologize to the readers that this was not detected during the submission process.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
