Abstract
nThis study explores a green approach to concrete production by using coconut shells and Manufactured Sand (M-Sand) as partial substitutes for traditional coarse aggregates and natural sand. Additionally, it investigates the role of silica in enhancing concrete properties. Coconut shells, often seen as waste, are utilized as lightweight aggregates, reducing the need for heavy natural aggregates. M-Sand replaces some of the natural sand, conserving this resource and reducing carbon emissions. To increase concrete’s strength and durability, silica is added. Lab tests, including gradation analysis, strength, workability, and durability assessments, determine the ideal mix proportions for these materials. The results show that coconut shells (up to 0-15%) and M-Sand (up to 0-100%) can effectively replace traditional materials without compromising concrete quality. This eco-friendly approach offers a sustainable alternative for the construction industry. It conserves resources, reduces the environmental footprint, and enhances concrete performance. For widespread usage, issues including long-term durability and quality control must be resolved. This study supports the worldwide movement for sustainable development by advancing more ethical and ecological building methods.
