A Preliminary Study on the Performance of Fly Ash Coating on M15 Block of Battery Waste Slag: Solidification/ Stabilization Process
Keywords: Leaching, Lead, Slag, Stabilization/ Solidification, Unconfined Compressive Strength.
AbstractA Solidification/ Stabilization performance of lead containing battery waste slag with cement matrix was studied. The samples of an industrial battery waste slag were used in experimental work. Heavy Metal Characterization of battery waste slag by Atomic Absorption Spectrometry (AAS) revealed that battery waste slag contains a certain percentage of lead and Chromium. Dissolving of the slag components causes migration of ions into water that can induce a significant pollution of environment. The influence of concrete block composition was the evaluated for fly ash coated and without fly ash coated block. For Mandatory requirement also available leaching test [NEN- 7341] to evaluate the leaching behavior of coated and without coated concrete block. The result revealed that Unconfined Compressive Strength were observed in the range of 6.51- 25.66 mpa without coated concrete block and coated block with 2.9 mpa - 17.67 mpa.
