ABSTRACT

This study aims at utilizing industrial wastes and mineral admixtures to improve the strength in single layer concrete filled aluminium tubular columns. This study also focuses on the effective ways of utilizing copper slag as fine aggregate replacement of 10% thereby reducing the pollution as well as meets the increasing demand of river sand for concrete. This experimental investigation indicates the compressive strength characterization at 28 days and the impact of mineral admixtures like metakaolin and GGBS in properties of concrete as a binder replacement of 5%, 10%, 15% and 20% respectively. The results obtained showed that the hybridization of natural minerals in combination with copper slag replacement can be incorporated in concrete to improve their mechanical strength of tubular columns.
