AN EXPERIMENTAL INVESTIGATION ON COPPER SLAG AS REPLACEMENT OF FINE AGGREGATE IN CONCRETE

Worldwide the average consumption of sand for construction increases 40 billion tones annually as sand is used as a conventional construction material. The large scale of extraction lead to cause impact in marine and biodiversity, so there is an immediate attention to be taken in construction industry to find an alternative construction material. The main objective of this investigation is to compare the strength parameter and behavior of fresh and hardened concrete with with conventional concrete and copper slag incorporated concrete in various percentages as replacement of fine aggregate. Approximately 24.6 million tones of copper slag generated at every year of copper production in worldwide (Gorai et al, 2003). The strength characteristics of copper slag incorporated concrete was found out by replacement of 20%, 40%, 60%, 80% and 100 %, out of this 40% replacement gives highest compression strength at 28 days, more than 37.55 % higher in Compression Strength and 5.3% higher in Split Tensile Strength and 40.72% in Flexural Strength compare to conventional mix.
