TL;DR: In this paper, the authors explored the chloride permeability and initiation of chloride induced corrosion of geopolymer concrete in accelerated chloride environment using longer test period, and showed that the apparent chloride diffusion coefficient of blended fly ash and slag-based concrete is lower than that of OPC concrete.

TL;DR: In this paper, the compressive strength of six types of geopolymer pastes made from different fly ash sources were studied via contour analysis, and it was shown that strength evolution mainly depends on the distribution of SiO2 and Al2O3 in the starter fly ash rather than their ratios.

TL;DR: In this paper, the role and relationship between SiO2 and Al2O3 contents of aluminosilicate material on the properties of Si-rich geopolymer systems using Australian fly ashes and existing published data.

TL;DR: In this article, a study of the setting time and rate of slump loss of geopolymer binders based on fly ash and slag blends and activated with pentahydrate and anhydrous sodium metasilicate is presented.

TL;DR: In this article, the potential re-use options for a suite of low rank brown coal fly ashes (ASTM class C fly ash) as feedstock for geopolymer binder synthesis were evaluated using a number of conventional characterisation tools.
