Abstract:
In the last decades studies have been carried out to characterize theleaching behaviour of coal ash in relation to disposal. As soon as the
beneficial properties became more and more recognized characterization also
took place in relation to beneficial applications of coal ash mainly in
construction. The main question has always been how leaching test results
could be used as a reasonable measure for its behaviour under field
conditions. Existing single step regulatory tests proved clearly inadequate
for that purpose. Therefore, leaching tests have been developed that address
the issue of release to the surroundings in a more fundamental manner, but at
the same time keep the approach as simple as possible to allow use of such
tests as a tool in decision making. 4 figs., 2 tabs., 18 refs.
