AN APPLICABILITY OF DEHYDRATED CAKE PRODUCED FROM QUARRY TO IMPERMEABLE MATERIAL WITH HEAVY METAL ADSORPTION
For impermeable materials for landfill constructed at intermountain region, clayey materials supplied homogeneously and stably are required. Authors have paid attention to the dehydrated cakes mainly produced from quarry at intermountain region. Then, new impervious material with an additive which allows absorbing heavy metals has been developed. According to the previous studies, it was confirmed that the landfill standard regarding sealing work could be secured by the compaction of two kind of different dehydrated cakes with the constant condition of water content. Now, there are approximately 1,500 quarries in Japan and each lithological character is different. Whether such differences of lithological character are problematic to the usage as impermeable materials is an important issue to be examined. Moreover, this paper describes the results of the examination in terms of the following three points. (1) The water content and the degree of compaction on the trafficability and permeability properties, (2) Evaluation of long-time durability (3) This material have the heavy metal adsorption ability.
