Abstract
The properties of lightweight concrete containing pumice treated with sodium hypochlorite (NaOCl) were experimentally investigated in this study. The study used treated pumice as 100% replacement of fine and coarse aggregates in concrete mixtures. Untreated pumice aggregates were used to prepare reference mixtures. In addition, the study investigated the effect of sodium hypochlorite on pumice properties. The concrete compressive strength at ages of 7 and 28 days was tested. The results showed that the compressive strength of concrete that contained treated pumice increased by 200% as compared to concrete containing untreated pumice. The pumice aggregate treated with NaOCl increased the pumice strength and improved its physical characteristics as the mean of specific gravity and abrasion resistance.
期刊介绍：
I am very pleased and honored to be appointed as an Editor-in-Chief of the Jordan Journal of Civil Engineering which enjoys an excellent reputation, both locally and internationally. Since development is the essence of life, I hope to continue developing this distinguished Journal, building on the effort of all the Editors-in-Chief and Editorial Board Members as well as Advisory Boards of the Journal since its establishment about a decade ago. I will do my best to focus on publishing high quality diverse articles and move forward in the indexing issue of the Journal.
