| Description
| - Main goal of the study was to describe properties of sludge stabilized by Portland slag cement. Prepared products of stabilized/solidified waste with three different contents 12 wt. %, 20 wt. % and 30 wt. %, respectively, of Portland slag cement were evaluated in accordance with valid waste legislation,, mobility of monitored elements and from the aspect of development of mechanical strength after 2, 7 and 28 days of hydration. Leaching tests including procedures of sequential extraction and X-ray diffraction were the main techniques and evaluaton methods used in the research. Obtained results of sequential extraction providing information about mobility potential and bioavailability of studied metals revealed, that the Zn content of untreated sample in the most accessible ionto-exchange and carbonate fraction reached 8x higher concentration than the appropriate concentration limit for hazardous waste. Results of determined compressive strengths of the S/S products indicated increasing of compressive strength with time and amount of added Portland slag cement. After 28 days of hydration the products contained phase of gismondine, independently on a quantity of the added binder. Immobilization of metals monitored by procedure used occurred already within two days in the process of solidification of the wastes and binder mixture and it was even more distinct with higher amount of added binder.
