Laboratory Findings of Aluminium Refinery Residue (ARR) Stabilized with GGBS and Alkali Solution
Abstract
Aluminium Refinery Residue (ARR) is the residual product generated during the manufacturing process of Alumina. The Bayer process is most commonly adopted to extract alumina from the ore bauxite. Globally, nearly 3 billion tons of Aluminium Refinery Residue (ARR) is stored. The storage of untreated Aluminium refinery residue consumes more open land for storage. The present article discusses the material properties like grain size analysis, consistency limits, specific gravity, maximum dry density, optimum moisture content, unconfined compression strength test, and durability properties of stabilized Aluminium refineries residue with ground granulated blast furnace slag (25%), a combination of alkaline solution at 5% Na2O, Silica modulus and its probable application as road construction material. Results have shown an increase in UCS (average 381%) values of the stabilized ARR at 0,7 and 28 days of curing compared with same day cured sample and Problems associated with the earthen road construction material is the reduced strength and weathering due to exposure to harmful climatic conditions. So the prominence has been given to the durability of the stabilized Aluminium Refinery Residue (ARR) by considering the effect of Wetting and Drying (W and D) cycles on its weight loss which is within the limits as specified by codes.
