SUPER concrete poontoon is developed to overcome shortcomings about corrosion problem of steel poontoon and the insufficient freeboard line of concrete poontoon. The top slab resists for truck load or sidewalk live load. And the soffit slab and outer wall resist for horizontal and lift components of wave pressure. The optimum characteristic compressive strength of SUPER concrete poontoon is analyzed 100Mpa. SUPER concrete poontoon have advantageous durability compared with the steel or general strength material in a lot of Chloride Exposure at offshoer, These are checked by Fick's diffusion curve and depth of neutralization. Finally, SUPER concrete is alternative material for steel and concrete poontoon.
