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