Abstract
A large amount of waste contaminated by radioactive cesium was released from Fukushima daiichi nuclear power plant due to the great east japan earthquake. The objectives of this study were to examine the permeability characteristics and water adsorption properties of a geo-material . In this study, Tokuyama clay was mixed with different proportions of bentonite and steel slag. Results revealed that the coefficient of permeability decreases with the increase of bentonite and that increases with the adding of steel slag. The adsorption performance was found to be decreased with the adding of bentonite. In contrast, the adsorption performance was comparatively increased with the adding of steel slag.
