        abstract = {The accumulation of aluminum waste, particularly discarded bottle caps, presents environmental challenges and encourages the exploration of sustainable construction materials. This study investigates the feasibility of using waste aluminum bottle caps as a partial replacement for coarse aggregate in concrete. The aluminum caps were collected, cleaned, and processed before being incorporated into concrete mixes at various replacement percentages of coarse aggregate. Standard tests were conducted to evaluate workability, density, and compressive strength of the concrete, and the results were compared with conventional concrete. The findings indicate that partial replacement of coarse aggregate with aluminum caps can reduce concrete weight and promote recycling of waste materials. An optimum replacement level was identified where acceptable mechanical performance and sustainability benefits were achieved. The study concludes that aluminum bottle caps can be effectively utilized in concrete for lightweight and non-structural applications, contributing to environmentally friendly construction practices and waste reduction.},
