Abstract: The present invention relates to a sustainable concrete composition utilizing Tamarind Seed Powder as a partial replacement of cement in concrete. Tamarind seeds, an agro-industrial waste generated in large quantities from food processing industries, are processed into fine powder and used as supplementary cementitious material. In a preferred embodiment, tamarind seed powder replaces 8% by weight of cement, providing an optimized balance between mechanical strength, workability, durability, and environmental sustainability. The tamarind seed powder contains natural polysaccharides, silica traces, and carbonaceous compounds which contribute to micro- filling action and improved particle packing in the cement matrix. The invention enhances compressive strength, split tensile strength, flexural performance, water resistance, and crack resistance when compared with conventional concrete. The invention further provides a controlled methodology involving drying, roasting, grinding, sieving, and proportionate blending of tamarind seed powder with cement. The developed concrete exhibits reduced permeability, improved long-term strength, lower heat of hydration, and reduced carbon footprint due to cement savings. The invention promotes sustainable construction through utilization of agricultural waste and reduced dependence on Portland cement. The composition is suitable for pavements, residential buildings, precast blocks, pavers, retaining walls, and general structural applications.
