Possible applications of hardening slurries with fluidal ashes in environment protection structures

Open access


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.
