The construction industry faces growing challenges in developing sustainable and durable materials, particularly for infrastructure exposed to aggressive coastal environments. This study explores the potential of bio-concrete incorporating ceramic waste, recycled glass, and agricultural by-products to enhance mechanical strength and durability. Experimental results indicate significant improvements in flexural and tensile strength, increasing from 2.5 MPa to 6.0 MPa and 2.0 MPa to 4.6 MPa, respectively, over curing periods of 7, 28, and 56 days. Additionally, chloride ion penetration resistance and sulfate durability tests demonstrated enhanced performance, with minimal mass loss and strength reduction, reinforcing the material's suitability for sulfate-rich environments. The incorporation of these alternative materials positively influenced the concrete matrix, contributing to long-term structural integrity. This research highlights the feasibility of sustainable bio-concrete as an environmentally friendly alternative to conventional concrete, offering enhanced durability for coastal and marine infrastructure applications.
