Jarosite, one of the by-product of zinc manufacturing industry has been of a major concern in this context because of its hazardous nature. The present study aims to assess the durability of cement concrete containing jarosite. Fine aggregates have been replaced by jarosite in different percentages. Equivalent volume of 25% cement has also been replaced by fly ash. Durability parameters like chloride diffusion and corrosion in jarosite were determined. Keeping the environmental suitability of concrete in mind, toxicity leaching characteristic potential test has been performed on raw jarosite and concrete samples. It was observed that the chloride diffusion in concrete and corrosion of reinforcement in jarosite added concrete has been less than control mixtures. The satisfactory performance of durability properties has been validated with the Scanning Electron Microscopy images and X-ray diffraction.
