Fly ash-based geopolymers: the relationship between composition, pore structure and efflorescence [PDF]
This study reports the observation of efflorescence in fly ash-based geopolymers. The efflorescence rate strongly depends on the activation conditions; at the same alkali content under ambient temperature curing, NaOH-activated geopolymers show less and ...

Performance of laterite-based geopolymers reinforced with sugarcane bagasse fibers
In this study, sugarcane bagasse fibres (SBF) were used as a sustainable alternative to reinforce laterite-based geopolymers. As geopolymers can be deemed an eco-friendly construction material, the sustainability of geopolymers can be further improved ...

Thermal Resistance Variations of Fly Ash Geopolymers: Foaming Responses [PDF]
This paper presents a comparative study of the characteristic of unfoamed and foamed geopolymers after exposure to elevated temperatures (200–800 °C). Unfoamed geopolymers were produced with Class F fly ash and sodium hydroxide and liquid sodium silicate.
