Abstract
This article presents ways of possible utilization and application of fl
uidal combustion wastes as active additives to hardening slurries which
are used to seal environment protection structures, i.e. cut-off walls in
waste dumps and wastewater treatment plants. Cut-off walls are often
exposed to fi ltrating action of eluates - polluted (aggressive) waters.
Results of hydraulic conductivity tests of slurries after their long-term
(210 days) fi ltration with eluates from a municipal waste dump and with
tap water are presented. Porosity tests were also conducted to show the
porosity structure of the fi ltered slurries. Additionally, compressive
strength of slurries maturing in tap water and waste dump eluates was
tested in parallel.
