1 Retraction note to: Materials and Structures (2021) https://doi.org/10.1617/s11527-010-9664-y
The Editor-in-Chief has retracted this Article.
After investigation, it has been found that Figures 2 and 3 show overlap with Figures 1 and 2 (respectively) of a previously published article by different authors [1].
Additionally, it has been found that some of the figures and tables have been reproduced in other, later-dated publications, and in some cases are identified in those publications as representing materials different from those described in the paper of concern. Specifically:
-
Table 1 showing the chemical and physical properties of Portland Cement has been duplicated in later publications [2,3,4] (among others) with no reference to this article;
-
Figures 2 and 3 appear identical to those published in [5, 6];
-
Figure 2 has similarities with Figure 2 in [3] when rotated, despite representing different nanoparticles;
-
Figure 7a has similarities with Figure 8(2)a of [7] and Figure 3a of [8]; and
-
Table 7 has been partially reproduced in Table 6 of [9] without any cross-reference.
For these reasons, the Editor-in-Chief no longer considers the data underlying the article to be reliable.
Ali Nazari has not responded to any correspondence from the Publisher about this retraction.
