Abstract The use of some environmental functional minerals as backfill-modified materials may improve the leaching resistance of cemented uranium tailings backfill created from alkali-activated slag (CUTB), but these materials may participate in the hydration reaction of the cementitious materials, which could have a certain impact on the pore structure of the CUTB, thus affecting its mechanical properties and leaching resistance. In this paper, natural zeolite is selected as the backfill-modified material, and it is added to alkali-activated slag paste (AASP) and CUTB in cementitious material proportions of 4%, 8%, 12%, and 16% to prepare AASP mixtures and CUTB mixtures containing environmental… More >
