  • Abstract:
  • Concrete has become widely used in various construction projects, ranging from small-scale residential buildings to high-power nuclear plants. Despite its versatility, conventional concrete has limitations, prompting the emergence of innovative types like Self Compacting Concrete (SCC), which exhibits fluid behavior and eliminates the need for external vibration during compaction. However, the widespread use of concrete as a building material contributes significantly to carbon dioxide emissions, posing a threat to atmospheric balance. In response, research endeavors to address this issue by developing a self-compacting concrete mix that offers both workability and durability. This is achieved by strategically substituting conventional cement with industrial waste materials such as cement kiln dust and fly ash. The study replaces a constant 30% of cement with fly ash and explores different percentages (5%, 10%, and 15%) of cement kiln dust replacement. After testing, it was found that a 10% replacement of cement kiln dust yielded the optimum performance in terms of compressive strength. Specimens were subjected to tests for compressive strength, split tensile strength, and flexure at 7 and 28 days, respectively. Comparison with conventional concrete revealed that the specimen containing 10% cement kiln dust replacement achieved the highest strength. Thus, the partial replacement of fly ash and cement kiln dust for cement proves to be a promising and sustainable alternative. This research contributes to reducing the carbon footprint associated with cement production, thereby fostering environmental sustainability.
