Abstract:
Concrete is a crucial construction material, but its environmental impact is significant, as cement production releases an equivalent amount of carbon dioxide per metric ton. To mitigate this, partial replacement of cement with mineral admixtures is an effective approach. Self-compacting concrete (SCC) is a specialized type of concrete known for its superior workability, enabling it to flow and compact under its own weight without external vibration. This enhances construction efficiency by improving filling ability, passing ability, and resistance to segregation. This study examines the performance of M40 SCC mixes incorporating fly ash as a supplementary cementitious material. The workability of SCC was evaluated through slump flow and L-box tests to determine its flow characteristics and passing ability. Mechanical properties, including compressive strength, splitting tensile strength, and flexural strength, were assessed at different curing ages. Durability performance was examined through water absorption and rapid chloride penetration tests, conducted for up to 28 days, to evaluate resistance to moisture ingress and chloride-induced deterioration. The results provide valuable insights into the effectiveness of fly ash in enhancing SCC properties, contributing to sustainable construction practices. The study also highlights areas for further research to optimize SCC performance and durability.
