From the point of view, longer life for Dam structures, it is necessary to carried out sediment of lake in bottom. That sediment is used to backfilling material, base course material, but some of them are not used effectively and have been piled up state. In this study, ASAKA-soil, which is kind of sediment, are applied to porous concrete of small particle size. Deciding setting void content by considering volume of cement paste per unit volume of concrete, evaluating compressive strength, void content and permeability coefficient.
Results of trial production for porous concrete of small particle size, practical product can be produced, but it is difficult to control void content. And when void content is about 20(%), permeability coefficient are about 10⁻³ order, it is expected that application in various field.
