Abstract
Utilization of high volume Copper Slag (CS) in concrete is the aim of present work. This study leads towards cleaner production; by utilizing industrial waste i.e. CS. The objective of the present paper is to make High Strength Concrete (HSC) by utilizing CS as Fine Aggregate (F.A). The work was carried in two phases. In first phase, sand was replaced with CS in various percentages of 0%, 20%, 40%, 60%, 80% & 100%. In second phase, cement was replaced with Nano silica (1%, 2% & 3%) to get maximum strength & impermeable concrete. Performance of concrete mixtures containing CS and Nano silica (NS) in terms of compression, split tensile & flexural strength and durability characteristic like water absorption were also identified. From all these studies it could be determined that replacing F.A with 100% CS in HSC was technically viable.
