A Preliminary Study on the Performance of Fly Ash Coating on M15 Block of Battery Waste Slag: Solidification/ Stabilization Process

Leaching, Lead, Slag, Stabilization/ Solidification, Unconfined Compressive Strength.Abstract
A 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.
