The evolution of strength and crystalline phases for alkali-activated ground blast furnace slag and fly ash-based geopolymers
TL;DR: In this paper, the increase in strength and evolution of crystalline phases in inorganic polymer cement, made by the alkali activation of slag, Class C and Class F fly ashes, was followed using compressive strength test and synchrotron X-ray diffraction in order to increase the crystallinity of the product.
Journal ArticleDOI
Effect of Curing Temperature and Silicate Concentration on Fly-Ash-Based Geopolymerization
TL;DR: In this paper, the pore structure of fly-ash-based geopolymers was studied using electron microscopy and porosimetry, showing that higher curing temperature increases the extent and rate of reaction, shown through an increase in mesopore volume, surface area, and an accelerated setting time.

Atlas of Zeolite Structure Types
TL;DR: The number of known and topologically distinct tetrahedral networks has risen to 64 and is expected to continue to increase at the rate of at least three per year as mentioned in this paper, with the advent of modern methods of structure solving, in particular powder techniques including ab initio structure determinations and Rietveld refinements.

Mechanism of zeolite synthesis from coal fly ash by alkali hydrothermal reaction
TL;DR: In this article, the mechanism of zeolite crystallization and the role of alkali solution on the synthesis reaction were considered. And the changes in various physical and chemical properties, such as crystal structure, surface structure and cation exchange capacity, of the obtained zeolites and the dissolved amount of Si 4+ and Al 3+ in alkali solutions were investigated during the hydrothermal reaction.
