Dependence of concrete properties on secondary lead slag share and additive type selection

Abstract

Automotive batteries are a major source for secondary lead processing, followed by generation of hazardous waste such as secondary lead slag. It has been used in presented research in a cement based stabilization/solidification process for the manufacture of concretes. The dependence of concrete properties with slag (10%, 20%) and additive (MgO, CaO, Ba(OH)2, CaSO4∙CaO) on the properties of concrete has been studied by measuring the compressive strength and lead leachability by TCLP method. Stabilization/solidification of secondary lead slag in concrete was most effective with 10% of slag as replacement of 15% aggregate and magnesium oxide as replacement of 5% cement.
