Study of In Situ Foamed Fly Ash Geopolymer

Study of In Situ Foamed Fly Ash Geopolymer

Foamed fly ash geopolymer was synthesized in this work to produce geopolymeric lightweight concrete (GLWC). Fly ash was activated by sodium silicate solution, and aluminum powder was employed as an in situ chemical foaming agent. The synthesized pastes were cured at 40 °C for 28 days, with bulk dens...
