Abstract:The building mortar was prepared with iron mine tailing sand substituted for natural sand, and the effect of tailing sand on the performances of mortar, such as consistency, stratification, density and strength, was investigated. The results show that it is feasible to prepare building mortar with iron mine tailing sand. The sediment percentage in tailing sand has relatively large effect on the fluidity of mortar, and the tailing sand should be washed with water before being used. When the mortar with low W/C … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
