TL;DR: In this article, the main cementitious gels forming during the alkaline activation of hybrid cements (70% FA/30% OPC) were characterised by different techniques.

TL;DR: In this article, a series of findings relating to the alkali-silica reaction are reported, and the results of SEM/EDX and XRD analysis of the materials showed that activated fly ash mortars performed better than the Portland cement equivalents.

TL;DR: In this paper, experiments were performed on blended cements containing 30% Portland cement clinker and 70% fly ash, where powdery material was mixed with deionised water for normal hydration, and with two different alkaline solutions for normal alkaline activation.

TL;DR: In this paper, the various components of two type F fly ashes are quantified using three techniques: chemical analysis with selective solutions, X-ray powder diffraction combined with the Rietveld method and nuclear magnetic resonance.

TL;DR: In this article, short-term effects of soluble alkali and aluminium, likely to be available in an alkali-activated system, on the structure of synthetic C-S-H gels are assessed.
