utylizacja składowiska - Opis:
- Stabilization/solidification (S/S) method is a potential solution for immobilization of heavy metals containing waste. Immobilization of heavy metals from spent grit, waste material from the shipbuilding and ship repair industry, into the fly ash based geopolymers using the S/S method was evaluated. Addition of spent grit in the quantity of 10% of total solid content of geopolymer mixture decreased the compressive strength of fly ash based geopolymers but did not affect the change of geopolymer strength in function of synthesis parameters. TCLP and EN 12457-2 leaching test were used for the evaluation of chemical stability of contaminated geopolymers with respect to the leaching of heavy metals. The both, TCLP and EN 12457 leachates fulfill the maximum acceptable limits for landfill disposal with respect to the heavy metals concentration. The highest concentration of Zn is observed in a both, TCLP and EN 12457 leachates due to the synthesis parameters.
