Characterization of Geopolymer Materials Containing MSWI Fly Ash and Coal Fly Ash
Advances in Science and Technology, 2010In this work three samples of MSWI ash have been stabilized in systems containing coal fly ash and able to give geopolymers through a polycondensation reaction. Monolithic products were obtained with both MSWI ashes as received and after chloride partial removal by water washing.

Abstract Fly ash is a waste material predominantly generated in the production of electricity. As a gigascale material, it represents a potential major environmental liability; however, because of its bulk mineralogy and chemistry, it can serve as a source of materials for large-volume, low tech applications.

2007 IEEE Industry Applications Annual Meeting, 2007
The possibility of converting fly-ash waste into a raw material for cement industry and other applications justifies the investigation of new beneficiation techniques, including those using electrostatic forces. The aim of this paper was to demonstrate the effectiveness of a modified roll-type corona separator in the processing of this material.

Mechanochemical treatment of fly ash and de novo testing of milled fly ash [PDF]
Environmental Science and Pollution Research, 2018 Mechanochemical (MC) treatment has been widely proposed to degrade chlorinated organics in various matrix materials. In this study, fly ash from municipal solid waste incineration was grinded without any addition, using an all-dimensional planetary ball mill.

Fly ashes, suspended in the exhaust gases, can be collected by electrostatic precipitators or baghouse filter. On the other hand, the portion of the non-combustible residues from combustion in an incinerator or furnace that fall by themselves to the bottom hopper of a furnace or incinerator is referred as bottom ash. Both the fly ash and bottom ash can

The aim of this study is to investigate the pozzolanic and cementitious characteristics of circulating fluidized bed combustion (CFBC) fly ash and the properties of cement-based composites with various combinations of CFBC fly ash and coal-fired fly ash. Setting time test, compressive strength test and length change test were performed to measure fresh

Beneficiated Fly Ash Versus Normal Fly Ash or Silica Fume
SP-242: 9th Canmet/ACI Fly Ash Conference, 2007The results of this paper indicate that a beneficiated fly ash (BFA) with a low carbon content, very fine particle size, and a more favorable shape of the small spherical particles, could be used instead of silica fume (SF) for high performance concrete.

Effects of Intergrinding Fly Ash on the Sulfate Resistance of Fly Ash Concrete
"SP-132: Fly Ash, Silica Fume, Slag, and Natural Pozzolans and Natural Pozzolans in Concrete - Proceedings Fourth Interna", 1992The interdependencies of the chemical and physical characteristics of fly ash concrete as they affect sulfate resistance is being studied. Both ASTM Type I and Type II cements have been partially replaced by both ASTM Class F and Class C fly ashes. Cement replacement levels of 25 and 35 volume percent have been studied.

Fly ash disposal and utilization
Journal of Chemical Technology & Biotechnology, 1990AbstractThis paper presents a general review on the problem of the so‐called ‘fly ash’ deriving from the combustion of fossil coal for energy production.Preliminary information is given on the actual coal consumption for the aforesaid purpose as well as on the corresponding fly ash generation, with further regard to its average composition and other ...
