Behavior of low-calcium fly and bottom ash-based geopolymer concrete cured at ambient temperature
Tianyu Xie,Togay Ozbakkaloglu +1 more
TL;DR: In this article, the behavior of fly ash-, bottom ash and blended fly and bottom ash-based geopolymer concrete (GPC) cured at ambient temperature was investigated. And the results indicated that the selected parameters significantly affect the microstructure and behavior of GPCs, resulting in the inferior behavior of the former compared to the latter.
Journal ArticleDOI
Synthesis and characteristics of fly ash and bottom ash based geopolymers–A comparative study
TL;DR: In this article, the authors developed mortars and concrete from fly ash and bottom ash and compared the characteristics deriving from either of these products by mixing the ashes with sodium silicate and sodium hydroxide as activator solution.
Journal ArticleDOI
Compressive strength and microstructural analysis of fly ash/palm oil fuel ash based geopolymer mortar
TL;DR: In this article, the effects and adaptability of palm oil fuel ash (POFA) as a replacement material in fly ash (FA) based geopolymer mortar from the aspect of microstructural and compressive strength was presented.

The geopolymerisation of alumino-silicate minerals
Hua Xu,J.S.J. van Deventer +1 more
TL;DR: In this paper, the effect of mineral properties on the compressive strength of the synthesized geopolymer was investigated, and it was shown that a wide range of natural Al-Si minerals could serve as potential source materials for the synthesis of geopolymers.
