Concrete is widely used in construction for its adaptability and ease of molding, supported by its fluidity in early stages. Proper compaction, typically achieved through vibration, is essential to ensure strength and durability by minimizing voids. Designing self-compacting concrete (SCC) is more complex, requiring careful selection and dosage of compatible materials to achieve desired flowability and homogeneity. This study presents an experimental investigation into SCC incorporating various construction wastes—concrete, marble, glass, brick, and dune sand powders—as partial replacements. SCC mixes were prepared with 40% concrete waste powder, 40% marble powder, 40% glass powder, 15% brick powder, and 25% dune sand powder, and were compared to ordinary concrete. The primary aim is to valorize construction waste as sustainable additives for SCC, promoting environmental preservation by reducing landfill waste and conserving natural resources. The results showed that SCC with brick, marble, and glass powders significantly improved performance. Notably, brick powder yielded the best overall results, while glass powder demonstrated superior resistance in the permeability test.
