| Research Abstract |
(1) In order to create uniform dredged soil blocks, it is necessary to shortening dehydration time.
(2) There is close relationship between unconfined compressive strength and water-cement ratio. Therefore, it is concluded that unconfined compressive strength of dredged soil blocks are controlled by water-cement ratio.
(3) Since the unconfined compressive strength exceeded 20MPa for more than cement content 22% in exposing test for 12 months, it is considered that dredged soil blocks have the sufficient durability.
(4) The number of species of sessile organisms at dredged soil blocks exposed to tidal area and under seawater is equivalent to other marine structures. Therefore, dredged soil blocks can be alternatively used for construction material of marine structures such as concrete brick and block.
