| Abstract | In recent years, zinc production has grown exponentially, compensating for the need arising from worldwide industrial growth. Jarosite is a non-biodegradable mineral residue obtained from smelting zinc ore. Jarosite is categorised as a hazardous material due to its high metal ion concentration, and hence, the safe disposal of massive volumes of jarosite waste poses a significant burden. This review article highlights how various proportions of jarosite affect concrete's fresh, mechanical, hydration, microstructural, and durability properties. When used in specific volumes, jarosite positively impacts the concrete compressive strength. The hydration mechanism of jarosite-incorporated concrete justifies forming a secondary hydration reaction, which causes dense morphology observed during microstructure analysis. Further, when jarosite is incorporated into concrete, the leaching characteristics of raw jarosite are observed to be substantially reduced and meet the safe limits. Based on the observations, a jarosite replacement level of 15% to the cementitious mix shows improvement in the mechanical and durability properties of the concrete. These findings could be used to identify a sustainable approach to reutilise the zinc industry waste by-products (jarosite). The experimental values of jarosite-incorporated concrete were compared with those of similar well-researched industrial waste materials such as red mud and copper slag to ensure that the observation and evaluation are accurate and trustworthy. |
