Demand for cement has surged because of the rapid urbanization and infrastructure development. To solve this serious dilemma, the construction sector is increasingly turning to supplementary cementitious materials (SCMs) which can partially substitute Portland cement in concrete compositions. These solutions need lower processing temperatures or leverage industrial by-products, thereby dramatically reducing the overall embodied carbon of concrete while maintaining or even improving performance qualities. By incorporating supplemental materials, the industry may achieve considerable emissions reductions without necessitating a total redesign of existing concrete technology, making it a feasible approach toward decarbonizing the built environment. To address these issues and promote sustainable construction methods, this study examines the combined use of Fly Ash (FA) and Bamboo Leaf Ash (BLA) as partial replacements for cement in M40-grade concrete. This research demonstrates that the thorough combination of Fly Ash with Bamboo Leaf Ash satisfies M40 grade requirements while advancing trash valorisation, lowering cement usage, and lowering carbon emissions, therefore improving sustainable and resilient concrete technology for modern structural applications. After 7, 14, and 28 days, concrete samples were tested to determine their strength. Their long-lasting performance was examined using tests including how far carbonation had penetrated for durability and various mixes of materials. While Bamboo Leaf Ash—a well-known pozzolanic by-product from thermal power plants—was kept at 10% by weight of cement in all altered mixtures, Fly ash, a well-known pozzolanic by-product from thermal power plants, was added at progressively higher levels of 0%, 3%, 6%, 9%, 12%, and 15% by weight of cement. The made concrete mixtures were: 0% BLA + 0% FA, 3% BLA + 10% FA, 6% BLA + 10% FA, 9% BLA + 10% FA, 12% BLA + 10% FA, and 15% BLA + 10% FA.
