Abstract |
Cement-based fixation systems are among the most commonly employed stabilization/solidification techniques. These cement waste mixtures, however, are vulnerable to acidic leaching solutions. Leaching of cement-based waste forms in acetic acid solutions with different acidic strengths has been investigated in the work. The examination of the pH profile along the acid penetration route by various pH colorimetric indicators is reported. A clear-cut leaching boundary of approximately 100 micrometers width was observed in every leached sample. (Copyright (c) 1992 Elsevier Science Publishers B.V.) |
