The effect of GGBFS and copper slag on strength of self compacting concrete: An experimental study

Abstract

The depletion of the natural resources and increased demand of constructional materials have always paved way for new advancements in the construction field. Engineers started research to find an alternative for the natural resources. Even though natural resources cannot be substituted completely, a partial replacement technique was introduced. Self-compacting concrete (SCC) can be defined as a fresh concrete which possesses superior flow ability under maintained stability, thus allowing self-compaction that is, material consolidation without addition of energy. Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration and it helps in achieving higher quality of surface finishes. However partial substitution of cement and fine aggregate by locally available waste materials like Ground Granulated Blast Furnace Slag (GGBFS) and copper slag have showed increase in the strength of SCC.
