  • Abstract:
  • Self-Compacting Concrete (SCC) is a specialized concrete that compacts solely through its own weight, eliminating entrapped air during pouring. This unique property grants SCC exceptional flowability, enabling it to fill voids and gaps effortlessly, even in densely reinforced areas, and maintaining a nearly horizontal level for uniform distribution and optimal structural integrity. SCC is particularly beneficial for complex formworks where conventional concrete struggles. It also incorporates industrial wastes like fly ash (FA) and cement kiln dust (CKD) as partial cement replacements, promoting sustainability and resource efficiency. Enhancing SCC's performance involves adding micro steel fibres in various percentages (0%, 0.25%, 0.50%, 0.75%, and 1%). These fibres improve the concrete's effectiveness by preventing crack propagation. Tests show that SCC without fibres excels in fresh properties, while SCC with 1% steel fibre demonstrates superior mechanical properties despite slightly reduced workability. Steel fibres also significantly reduce SCC shrinkage, boosting long-term durability and structural integrity. Analytical examination of RCC beams with varying steel fibre amounts using ABAQUS software indicates that SCC with 0.75% steel fibre provides the best balance of enhanced mechanical properties and manageable workability. Integrating steel fibres and industrial waste in SCC not only improves mechanical properties and durability but also supports sustainable construction by reducing reliance on traditional cement and promoting the reuse of industrial by-products.
