Sial geopolymer
WebThe advanced (SIAL®) geopolymer solidification technology offers an alternative route for problematic waste streams treatment. Their superior mechanical properties allow for … WebA fly ash based geopolymer with good mechanical strength was obtained through single factor experiments and the compressive strength of the geopolymer reached 29.72 MPa. The effects of immobilizing lead–zinc slag in the fly ash based geopolymer were discussed by means of compressive strength, leaching test and speciation analysis.
