Abstract:
Some bench-scale exploratory experiments were carried out to test theformation of precipitates, which are the basis of the self-forming and
self-repairing seal, in a dredge spoil/alkaline reactant system. Also it is
discussed how such a system can be applied on the slope, covered with slags,
of a planned dredge spoil deposit. The formation of calcite as the most
important sealing phase is proven. The calcite is formed by the reaction of
calcium from the alkaline reactant layer with carbon dioxide, which
originates from the decomposition of organic matter. The laying down of the
reactant layer on a slope, covered with slags for strengthening, appears to
be useful, although further research on this method is required. 4 figs., 5
