The amount of coal fly ash (FA) increases year by year, so, high volume FA usage is needed to avoid landfill disposal. In this study, to develop the civil engineering materials for harbor/port structures, the solidification material mixed with unburned pulverized shell(FA-Shell Block) was made without using cement. The pH of leaching water from the FA-Shell blocks (150×150×520 mm) was low alkalinity leaching around 8.5, and the compressive strength stayed high after 50 days soak in artificial sea water. Microalgal affinity of FA-shell block as comparisons rock and concrete was carried out under the running seawater for practical use. The adhesion properties of algal cells to surface of FA-Shell block was equal to concrete.
