Utilizing waste materials possessing pozzolanic properties in concrete production has become a global trend. Evaluating the pozzolanic activity of materials that replace cement is gaining significance due to the growing demand for environmentally sustainable cement products. Incorporating Bamboo Leaf Ash(BLA) as supplementary cementitious material(SCM) in concrete aligns with the principles of sustainable construction by reducing waste, utilizing renewable resources, and potentially lowering carbon emissions associated with traditional cement production. In this research work, BLA is used as partial replacement for ordinary Portland cement(OPC) in ranges of 10%, 20%, 30%. Fresh and hardened properties of concrete were investigated. Experimental results showed that, Concrete mix with BLA gives satisfactory cube compressive strength upto the replacement level of 20% with OPC as binder. Beyond 20% replacement, cube compressive strength falls below the characteristic strength of concrete.
