Development and incorporation of lightweight waste-based geopolymer aggregates in mortar and concrete
HighlightsLightweight geopolymer aggregates were manufactured from fly ash and mine tailings.Geopolymer aggregates have similar or better physical properties than LECAs.Rheology of the mortar paste is similar for LECAs and geopolymer aggregates.Geopolymer aggregates produced higher-strength mortars and concretes than LECAs.
AbstractUsing industrial side streams as artificial aggregate precursors could increase waste utilization and save natural reserves. In this study, lightweight geopolymer aggregates were manufactured from fluidized bed combustion fly ash and mine tailings using high shear granulation and alkali activation. The results showed that geopolymer aggregates had physical properties comparable to commercial lightweight expanded clay aggregates (LECAs). Mortar and concrete prepared with geopolymer aggregates had higher mechanical strength, a higher dynamic modulus of elasticity, and higher density than concrete produced with LECAs, while the rheology and workability was the same.
