Abstract
Highly impermeable geomaterials which will be used in coastal waste disposal sites can be constructed only by pumping installment. For this reason, the fluidized materials of high water contents must satisfies the requirements of no water pollution and no discontinuity under water as well as high impermeability at the time of their installation.
Based on a series of experimented work by the use of sea bed clays mixed with bentonite or sand, a new method to define the mixture design of them has been proposed on the basis of only the liquid limit of the mixtured material.
