Mechanical And Bond Characteristics Of Granulated Lead Smelter Slag Concrete

The environmental impact due to the production of Portland cement has prompted research into the utilization of industrial waste materials in the concrete industry. Mechanical properties and bond characteristics are essential, in particular the bond between concrete and steel. This paper presents the results of an experimental study carried out to evaluate the mechanical and bond properties of granulated lead smelter slag (GLSS) concrete. The experimental program involved the investigation of the compressive-strength development, the stress–strain relationship, splitting and flexural tensile strengths and bond stress. The results showed that GLSS concrete exhibits similar mechanical performance to that of fly ash and ordinary Portland cement (OPC) concretes. The results of bond stress are subsequently compared to predictions from models developed for OPC and fly ash concretes. The comparison suggests that the models provide reasonably accurate predictions for the bond stress of GLSS concrete.
