Abstract

This paper estimates the durability of water-swelling materials that is an important element in water cutoff performance of vertical cutoff walls constructed in coastal waste landfill sites. We carry out accelerated deterioration tests on the water-swelling materials. Furthermore, we predict the durability of water-swelling materials based on Arrhenius law. When Arrhenius law is applied to the result of accelerated deterioration test, the life of water-swelling materials will be estimated about 27 years. This suits the previous results in which decreasing in strength of water-swelling materials will not advance after progress from their curing start for one year. Therefore, it is thought that waterswelling materials are utilizable enough as water cutoff materials of vertical cutoff walls constructed in waste landfill sites for tens of years.
