HDPE‐Fly Ash/Nano Fly Ash Composites

Journal of Applied Polymer Science, 2013
ABSTRACTFly ash (FA) based polymer composites are assuming increasing importance because of its potentiality, fine particle size and plenty availability of FA. FA is mainly a mixture of inorganic metal oxides such as SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, TiO2, and so forth. This article highlights the results of the various modifications onto the HDPE‐FA/

Selenium in Fly Ash

Science, 1976
Selenium, at concentrations exceeding 200 parts per million (ppm) (dry weight), has been found in white sweet clover voluntarily growing on beds of fly ash in central New York State. Guinea pigs fed such clover concentrated selenium in their tissues.

Fly ash erodibility

Journal of Soil and Water Conservation, 1989
In the northeastern United States, fly ash is removed from stack gases and commonly trucked to landfills for disposal. The cover soil and especially the underlying fly ash of these landfills are susceptible to erosion by water. Fly ash erodibility was estimated by collecting sediment eroded by natural rainfall in the field from standard erosion plots ...

Permeability of Fly Ash and Fly Ash-Sand Mixtures

1985
In an experimental program aimed at evaluating the potential of fly ash for use in liners, permeability tests were performed on two pozzolanic fly ashes from western U.S. coal sources compacted at varying densities and mixed in varying percentages with a quartz sand. Permeability testing was performed in a falling head, flexible membrane, triaxial cell

Laboratory compaction of fly ash and fly ash with cement additions

Journal of Hazardous Materials, 2008
The use of power-industry wastes as a material for earthen structures depends on its compactibility. It has been confirmed that a fly ash/bottom ash mix compacted several times in Proctor's moulds are not representative. The relationship between dry density of solid particles and water content for re-used waste samples was determined. The re-compaction

Carbonitridation of Fly Ash. 4. Hydrolysis of Nitrided Fly Ash

Industrial & Engineering Chemistry Research, 2005
Hydrolysis experiments of the nitrided fly ash were carried out in dilute aqueous suspensions. An ammonium electrode and a pH electrode were used to measure the extent of the hydrolysis. For comparison purposes, hydrolysis studies were also performed for the commercially available nitrides.

Grindability of CFBC Fly Ash and High Temperature Fly Ash

Key Engineering Materials, 2016
This article presents the results of fly ash from Circulating fluidized Bed Combustion (CFBC) and high temperature fly ash (defined in EN 450-1) with modified physical parameters by grinding. For this treatment was used the mechanical mill. In this case were used two fly ashes.

Fly ash effects: I. The morphological effect of fly ash

Cement and Concrete Research, 2003
The morphological effect is an important part of fly ash effects. The paper analyzes emphatically this effect and points out that it is composed of the filling role, surface role and lubricating role. For different fly ash, these roles are different. They must be considered synthetically when the morphological effect is analyzed. Analyzing result shows
