(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.

（1）为了产生均匀的疏and土壤块，有必要缩短脱水时间。（2）无限制的抗压强度和水污等比率之间存在密切的关系。因此，得出的结论是，挖土土壤块的不合同性抗压强度由水泥浆比控制。（3）由于未经限制的压缩强度超过20mpa，超过水泥含量超过水泥含量为22％，在12个月中暴露了测试，因此被认为疏and的土壤块具有足够的耐用性。等效于其他海洋结构。因此，疏and的土壤块可以用于海洋结构的建筑材料，例如混凝土砖和块。
