Characterization of Geopolymer Materials Containing MSWI Fly Ash and Coal Fly Ash

Advances in Science and Technology, 2010
In 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.

The Recycling of the Coal Fly Ash in Glass Production

Journal of Environmental Science and Health, Part A, 2006
The recycling of fly ash obtained from the combustion of coal in thermal power plant has been studied. Coal fly ash was vitrified by melting at 1773 K for 5 hours without any additives. The properties of glasses produced from coal fly ash were investigated by means of Differential Thermal Analysis (DTA), X-ray Diffraction (XRD) and Scanning Electron ...

Characterization of Mutagenic Coal Fly Ash and Extracts

International Journal of Environmental Analytical Chemistry, 1982
Post-electrostatic precipitator (ESP) fly ash samples were collected from a coal-fired electric power generation plant under three modes of plant operation: normal operation, a low NOx-emission mode of combustion, and operation with the ESP shorted-out.

The Occurrence of Quartz in Coal Fly Ash Particles

Inhalation Toxicology, 2000
In spite of the presence of quartz, coal fly ash can be considered as a nuisance or inert dust. Respirable crystalline silica (e.g., quartz) is notorious for the induction of, for example, progressive massive fibrosis (PMF); besides, in 1997 the IARC stated that crystalline silica in the form of quartz or cristobalite from occupational sources is ...

Cytotoxicity of inhaled coal fly ash in rats

Environmental Research, 1987
The effect of inhalation of coal fly ash for 6 hr daily for 15 days has been studied on the hematology, blood chemistry, and histopathology of lungs and liver of rats up to 4 months from the first day of exposure. Fly ash inhalation significantly reduced WBC, RBC, and hemoglobin contents at earlier periods after exposure but tended to return to normal ...

Radioactivity of coals and fly ashes

Journal of Radioanalytical and Nuclear Chemistry, 2007
The level and the behavior of the naturally occurring primordial radionuclides 238U, 226Ra, 210Pb, 232Th, 228Ra and 40K in coals and fly ashes are described. The activity concentrations of the examined coals and originated from coal mines in Greece ranged from 117 to 435 Bq·kg−1 for 238U, from 44 to 255 Bq·kg−1 for 226Ra, from 59 to 205 Bq·kg−1 for ...

Coal fly ash as a pozzolan

2017
This chapter provides information on the use of coal fly ash as a pozzolan in concrete. Fly ash can be used to partially replace Portland cement in concrete, and its use provides many technical, economic, and environmental benefits. The characteristics of fly ash and the pozzolanic reaction are described.

MSW fly ash stabilized with coal ash for geotechnical application

Journal of Hazardous Materials, 2000
The solidification and stabilization of municipal solid waste (MSW) fly ash for the purpose of minimizing the geo-environmental impact caused by toxic heavy metals as well as ensuring engineering safety (strength and soaking durability) are experimentally evaluated.

Mobility of trace elements in fly ash and in zeolitised coal fly ash

Fuel, 2015
To investigate for the influence of zeolitisation on the mobility of trace elements (As, Cd, Co, Cr, Cs, Cu, Mn, Ni, Pb, Se, V, and Zn) from coal fly ash, two samples of fly ash (FA and FB) were submitted to leaching tests as well zeolitic fly ash (ZFA and ZFB) that was synthesised from FA and FB.

Properties of Concrete Incorporating Coal Fly Ash and Coal Bottom Ash

Journal of The Institution of Engineers (India): Series A, 2019
Million loads of coal wastes are being generated everywhere across the globe in the form of fly ash and bottom ash. Utilization of such waste materials in concrete is an eco-friendly choice. Therefore, the objective of the current experimental investigation is to explore the effects of fly ash and bottom ash on the properties of concrete by replacing ...
