This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of editor-in-chief. The editors no longer have confidence in the data presented in this paper. Following a whistle-blower complaint, an investigation indicated extensive reuse of SEM and sample images in this paper [A] from previously published [B] https://doi.org/10.1016/j.jclepro.2016.12.168. The papers report two different materials. Specifically, Figure 17b in Paper [A] is the same as Figure 12b in Paper [B] and has been further reused in a number of other articles including previously retracted paper [C] https://doi.org/10.1016/j.conbuildmat.2017.03.109. Portions of Figure 19 in Paper [A] are the same as Figure 12 in Paper [B]. Figure 20 in Paper [A] is the same as Figure 11c in Paper [B] despite the data being reported for different elevated temperatures. Figure 21 in Paper [A] is the same as Figure 12c in Paper [B]. Two images in Figure 7 of Paper [A] are repeated from Figure 5 in Paper [B]. The corresponding author denies the duplication.
