Quantitative determination of fly ash in the hydrated fly ash - CaSO4·2H2OCa(OH)2 system
TLDR
For the quantitative determination of fly ash in hydrated fly ash - CaSO4·2H2OCa(OH)2 system, various kinds of selective dissolution were evaluated using pastes made from a single representative fly ash as mentioned in this paper.About:

Degree of hydration and gel/space ratio of high-volume fly ash/cement systems
TL;DR: In this article, the degree of hydration of the cement in Portland cement (PC) paste was obtained by determining the non-evaporable water (Wn) content of the fly ash.

A study on high strength concrete prepared with large volumes of low calcium fly ash
TL;DR: In this article, the authors presented the results of a laboratory study on high strength concrete prepared with large volumes of low calcium fly ash, and the results demonstrated the dual effects of fly ash in concrete: (i) act as a microaggregate and (ii) being a pozzolana.

Rate of pozzolanic reaction of metakaolin in high-performance cement pastes
TL;DR: In this paper, the hydration progress in metakaolin-blended high-performance cement pastes with age was assessed from the measurements of compressive strength, porosity, and pore size distribution, the degree of pozzolanic reaction, and the Ca(OH)2(CH) content of the MK-blending pastes at a water-to-binder ratio of 0.3.
Journal ArticleDOI
A study on the hydration rate of natural zeolite blended cement pastes
TL;DR: In this paper, the compressive strength, degree of pozzolanic reaction, and porosity of zeolite modified cement pastes were compared with those obtained from similar blended pastes prepared with silica fume and fly ash replacements.
Journal ArticleDOI
Quantification of the degree of reaction of fly ash
TL;DR: In this paper, the fly ash reaction in two different blended OPC-FA systems was studied using a selective dissolution technique based on EDTA/NaOH, diluted NaOH solution, the portlandite content and by backscattered electron image analysis.

Chemical Species in Fly Ash from Coal-Burning Power Plants
TL;DR: Fly ash specimens from four power plants in the Tennessee Valley Authority system have been separated into three matrices: glass, mullite-quartz, and magnetic spinel, revealing the magnetic component of fly ash is ferrite.
