Abstract

This study presents an experimental investigation on the effect of using different conductive fillers; steel shavings, carbon powder and graphite powder as partial replacement of fine aggregate (1%, 3%, 5% and 7% by volume) on the electrical, physical, mechanical and durability properties of structural concrete. The effect of including different conductive fillers on the properties of fresh and hardened concrete was evaluated (i.e. slump, air content, unit weight, compressive strength, splitting tensile strength and water absorption). Results showed that structural concrete with good electrical conductivity could be produced for various applications by incorporating appropriate conductive filler type and content. The produced electrically conductive concrete (ECC) showed different performance characteristics and could be used as a multifunctional material for different structural applications. A performance index (PI) approach was used to evaluate and select the most suitable concrete mixture of required performance(s) criteria for multifunctional structural applications.
