Influence of the Character of Fly Ash on the Fluidity of Fly Ash Cement Paste [PDF]

Journal of the Korean Ceramic Society, 2010
The Influence of the character of fly ash on the fluidity of cement paste with a polycarboxylic acid type superplasticizer was investigated in connection with the particle size distribution, unburned carbon content, specific surface area and shape of the fly ash.

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/

Fly Ash

2017
Fly ash is an industrial by-product deriving from electricity generating plants. It is the by-product of burning coal or lignite. Fly ash is one of the first artificial admixtures used for the production of concrete since the first decades of the 20th century.

Weathering of Fly Ash [PDF]

Nature, 1960
A CONSIDERABLE body of information is now available regarding the minerals present in fresh fly ash which are available to plants1,2. During combustion of the coal, adventitious clay minerals such as kaolinite are broken down, and a material is produced containing all the mineral constituents of coal, but with a very low cation exchange capacity (3 m ...

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

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.

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

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
