RETRACTED: Influence of nano-CaCO₃ addition on the compressive strength and microstructure of high volume slag and high volume slag-fly ash blended pastes

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). The article duplicates significant parts of a paper that had already appeared in Sustainable Materials and Technologies, Volume 20, July 2019, e00111, https://doi.org/10.1016/j.susmat.2019.e00111. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
