Title: Impact of solid waste and reject of industry on the earth environment and its remediation

Abstract

Each component of earth is closely related to each other and interchange their elemental constituents. If there is any change happened one component of earth it directly and indirectly effect the other component of the earth environment. Earth Lithosphere has full of various types of solid waste and reject of industry cement industry, health industry, mining industry and construction industry. Generation of industrial wastes in huge quantities has unrepairable impact on earth environment and climate change in for of global warming. Developing country like India require huge amount of landscape for dumping of the waste or rejects of industries. Thus efficient technology is required to recycled and reutilization of billions of metric tons per annum of these waste/ rejects. These waste/rejects have been utilized to develop the geopolymers for application in construction industry. Their physical and engineering properties have been estimated to predict their strength and durability. Strength parameter and micr-textures analyses of geopolymers have been analyzed by using X-ray Diffraction, X-ray fluorescence and SEM/ EDX to characterize their design of mixture. Experimental studies have been performed for utilization the waste/reject and industrial waste by-product GGBFS for the production of geopolymers and its engineering parameters evaluation for application as constructional material. The mixtures were prepared by replacing the rejected material with different percentages of GGBFS and activated with alkali concentrations (4, 6, 8 and 10M) of NaOH for preparation of the geopolymer. Unconfined compressive strength has been obtained for all prepared mixtures that are cured at 7, 28 and 56 days either polythene or water curing method. Mineralogical constituents and micro textural performed to know their porosity and permeability.
