Properties of materials dedicated for the construction of isolation plugs-barriers in underground workings connecting an underground nuclear waste repository with a ground surface

Abstract

The paper presents results of tests of basic properties of selected materials dedicated for the construction of artificial isolation barriers in underground workings, which connect an underground disposal site with a surface of the ground. The modified waste from coal fired power generation plants have been considered as a potentially useful materials for this application.
