A Comprehensive Review on Lead-Zinc Tailings as An Alternate Material in Concrete

Abstract

Lead-Zinc Tailings are high volume wastages that are dumped in the open area of mine after extraction of minerals from ore. Tailings have high content of heavy metals that creates lot of environmental problems like air, water, land and also marine drainage along with it creates risk to human life, so tailings required better and safe management to overcome these problems. Now, this review begins with the utilization of Lead and Zinc Tailings as an alternate material in the concrete production by replacing Cement and Fine aggregate. The previous studies shows that tailings have been used as an alternate material for cement and sand, the compressive strength of the material with Lead and Zinc is increased while increasing curing days and the workability of material is reduced. So, the compressive strength of material is reduced when we are increasing the tailing content in the concrete. Finally, the results show that, the tailings-based concrete have better result to overcome environmental problems and also introduction of new materials in the construction industry. This review gives an overview about Lead-Zinc tailings and comprehensive understanding of utilization of tailings as an alternate material in the preparation of concrete. There is a possibility to conduct more research on behavior and properties of Lead-Zinc tailing based concrete that is durability properties, microstructural properties, thermal properties, mechanical properties, and also leaching properties of the concrete. So, by utilizing Lead-Zinc Tailings as a replacement material we can introduce more new materials in the construction field and also reduces the environmental problems.
