Abstract

The paper presents the results of research and development of high-performance fine-grained concrete (HPFGC) for floating pontoons. Concrete Pontons have thin-walled structures and often work in water and seawater environments. The developed HPFGC has high flowability and can self-compact into the formwork, suitable for the construction of thin-walled structures such as floating pontoons. The amount of Silicafume used is from 0 - 15%, the amount of fly ash used is from 0 - 30% replacing the amount of cement used in HPFGC. The experimental research results show that it is possible to manufacture HPFGC using fly ash/silicafume with a compressive strength of 60 - 80 MPa. This HPFGC has high water impermeability and chloride ion resistance, suitable for floating pontoons working in water environments, including seawater environments.
