A study on utilization of jarofix in construction application

Abstract

newline Industrialization is the back born for the economic development of any country which leads to urbanization and infrastructure development. Worldwide,due to this urbanization and industrialization, enormous amount of wastes are generated. Presently in India, about 960 million tonnes of solid waste is being generated annually from various sources. This leads to environmental degradation, water pollution, soil pollution, and air pollution and will be a threat to human health. Jarosite is such an industrial waste generated during extraction of zinc ore concentrate by hydrometallurgy operation. This hazardous waste is mixed with lime and cement to get Jarofix which is also considered as hazardous under the Hazardous Waste Management Regulations. The leachate produced by Jarofix contains heavy metal concentrations beyond the safe limit suggested by pollution control board. Hence, its disposal has become a major environmental concern for the zinc industries. newlineRapid development also causes paucity and depletion of natural resources like soil, river sand, granite rock etc., which are unavoidable for the infrastructure development. At the same time, continuous exploitation of such materials will be a threat to the nature. Engineers are searching all over the world for finding alternate materials in construction industries to replace the usage of natural materials. The utilization of industrial waste is a solution to the same and it also helps to reduce the problems of waste disposal.Here an attempt was made to recommend the utilization of the industrial waste Jarofix in different fields of construction industry, by studying the various engineering properties of soil due to the presence of Jarofix through laboratory investigations.
