This study develops a lightweight floating concrete with optimized strength-to-density performance for marine and offshore structures like docks, marinas, and platforms. The mix incorporates cement, fly ash, expanded clay, expanded polystyrene beads, polypropylene fibers, and chemical admixtures to reduce density while ensuring compressive strength. Laboratory tests evaluated mechanical and buoyancy properties, including load-bearing floating tests on a 600 × 600 × 150 mm prototype. Results confirm the viability of this buoyant concrete for real-world use, offering a sustainable, durable alternative to conventional concrete for aquatic and offshore infrastructure.

摘要

This study develops a lightweight floating concrete with optimized strength-to-density performance for marine and offshore structures like docks, marinas, and platforms. The mix incorporates cement, fly ash, expanded clay, expanded polystyrene beads, polypropylene fibers, and chemical admixtures to reduce density while ensuring compressive strength. Laboratory tests evaluated mechanical and buoyancy properties, including load-bearing floating tests on a 600 × 600 × 150 mm prototype. Results confirm the viability of this buoyant concrete for real-world use, offering a sustainable, durable alternative to conventional concrete for aquatic and offshore infrastructure.
