Abstract: Concrete is the most widely used construction material in the world, and its production is responsible for a significant amount of CO2 emissions, making it a major contributor to global warming. Selfcompacting concrete (SCC) is a type of concrete that can flow under its own weight and fill all the spaces in the formwork without the need for external vibration, which makes it more sustainable compared to traditional concrete. In this study, the performance of SCC using Sugarcane bagasse ash (SCBA) and Ground granulated blast furnace slag (GGBS) as mineral admixtures was investigated for sustainable construction. The study focused on determining the optimum percentages of both SCBA and GGBS to produce SCC with enhanced properties. The SCC mix with SCBA10 GGBS20 achieved a compressive strength, which is significantly higher than the control mix without any mineral admixtures. The flexural strength and tensile strength of SCC mixes with SCBA10 GGBS20 were also higher than the control mix. In terms of durability, the SCC mixes with SCBA10 GGBS20 exhibited better resistance to water penetration, chloride ion penetration, and acid attack compared to the control mix. The UPV test results showed that SCC mixes with SCBA10 GGBS20 had a more uniform and dense structure, which indicates better overall durability. The study is aligned with Sustainable Development Goal 12 (SDG 12) of the United Nations, which aims to ensure sustainable consumption and production patterns. The optimal mix of SCBA10 GGBS20 can lead to the production of high- performance SCC, which is crucial for sustainable construction practices. In conclusion, this study demonstrates the feasibility of using SCBA and GGBS as mineral admixtures in SCC production to enhance its performance and sustainability. The study's findings provide valuable insights for researchers, engineers, and construction professionals to develop sustainable and costeffective concrete mixes for construction projects.
