Effect of Jarosite as Partial Replacement of Fine Aggregate in Pavement Quality Concrete Mixes
Due to lack of acceptable disposal locations for jarosite and incorrect disposal procedures, huge amounts of waste generated by the industrial sector harm the environment. However, in order to ensure the long-term viability of both concrete and industrial growth, the use of industrial byproducts as a raw material in concrete is becoming increasingly vital. Jarosite, a waste material formed during the extraction of zinc ore concentrate and widely available as a low-cost resource in Rajasthan, was employed as a partial replacement for fine aggregate in pavement quality concrete mixes in this study. The effect of replacing fine aggregate by jarosite material was investigated for pavement quality concrete mixes. The replacement level of jarosite with fine aggregate was varied from 0, 10, 20, 30% respectively in the pavement quality concrete having w/c ratio of 0.39. The fresh, hardened and durability properties of the pavement quality concrete were studied in the laboratory. The fresh properties in terms of compacting factor, hardened properties i.e. compressive strength, flexural strength and durability in terms of drying shrinkage and abrasion resistance were studied. The results indicate that the concrete, which contains 20% jarosite as a replacement of fine aggregate showed the highest compressive strength and flexural strength compared to the controlled concrete mixes, further replacement decrease the strength. The drying shrinkage of the all the jarosite blended concrete decreased with increasing content of jarosite. The abrasion resistance of the concrete decreased with increasing content of jarosite in the pavement quality concrete mixes. The study shows that jarosite has a potential to be used as fine aggregate in pavement quality concrete.
