Development of soil concrete to realize 3R society

为了有效地将疏浚粘土回收为有用的材料，作者开发了一种称为水泥搅拌和机械脱水法（简称CMD）的技术。在CMD程序中，软粘土与水泥混合，以高脱水压力脱水，以提高强度。本研究采用新研制的大型脱水设备（直径53.4cm，高度100cm）对CMD试样进行放大试验，评价其均匀性和强度性能。

In order to recycle dredged clay to useful material efficiently, authors have developed a technique called the cement-mixing and mechanical dehydration method (called "CMD"). In the CMD procedure, soft clay mixed with cement is dehydrated with a high dehydration pressure for the purpose of increasing the strength. In this study, scale-up test of the CMD specimens was carried out using newly developed large dehydration equipment (53.4cm in diameter and 100cm in height) to evaluate the uniformity and strength property.
