Leaching of cement-based waste form in acetic acid solutions has been investigated in this work. The examination of the pH profile along the acid penetration route by various pH colorimetric indicators is reported. A line of demarcation, believed to be the leaching boundary, was observed in every leached sample. (Copyright (c) 1991 Elsevier Science Publishers B.V.)
