📄 Abstract（原文）
Concrete is one of the most widely used construction materials due to its strength,durability,and versatility in infrastructure development. However, the rapid increase in construction activities has resulted in serious environmental concerns. Cement production contributes significantly to carbon dioxide emissions, which accelerates global warming,while excessive extraction of natural sand leads to ecological imbalance and depletion of natural resources. To address these issues, the development of sustainable concrete using alternative materials has become essential. This study focuses on the use of neem leaf powder as a partial replacement for cemnent and styrene-butadiene-styrene (SBS) polymer as a partial replacement for fine aggregate. Neem leaf powder,being an agricultural waste, acts as a microfiller and reduces porosity while improving durability. Additionally, it possesses antibacterial properties that enhance the long-term performance of concrete. On the other hand, SBS polymer improves ductility, flexibility, and crack resistance due to its elastic nature. The experimental investigation involves material testing, mix preparation,casting,curing,and evaluation of workability and compressive strength. The results indicate that partial replacement of conventional materials with eco-friendly alternatives reduces environmental impact while maintaining structural performance. The optimum replacement level is observed at 10%, where maximum compressive strength is achieved with acceptable workability. This study highlights the importance of sustainable construction practices and demonstrates the effective utilization of agricultural and polymer waste materials in concrete production. The research contributes to eco-friendly construction and promotes the development of cost-effective and durable building materials.
