Using Fly Ash in Concrete - precast

May 08, 2010 · The amount of fly ash used in a mix design also determines how much or how little early strength gain will be affected. The rate at which fly ash reacts also is dependent upon the coal the fly ash came from and the amount of silicon dioxide, aluminum oxide and iron oxide. Heat of hydration also affects early strength gain.

Environmental Justice Concerns Associated with Potential ...

prompted the passage of the Coal Ash Management Act of 2014, which addressed the environmental risk posed by coal ash by requiring Duke Energy to clean up their coal ash basins. Looking for a cheap way to essentially re-dispose of the coal ash, Duke Energy contracted out two clay mines to dump coal ash into as a beneficial re-use project.

Coal-Ash Chemicals in Your Drinking Water: Y/N? | Sierra Club

The Grahams live within a thousand feet of a pit holding waste from a coal-fired power plant (it converted to gas in 2013). Their water was polluted with vanadium and hexavalent chromium, two chemicals found in coal combustion residuals (CCRs)—also known as coal ash, what remains after coal is burned.

Ash Composition Influence on Fusibility of Coal Ash

The coal of Zichang was selected as the sample coal, the physical properties of the ash is analyzed with ICP-AES. The ash fusion temperature was researched by adding different basic oxide contents. The results show that the general trend is decrease firstly, and then increase when adding basic oxides. Blended ash fusion temperatures do not change linearly with blending ratios and ash fusion ...

Different CaO Content Influence on Fusibility of Coal Ash

Selecting the Zichang coal as the sample coal, the chemical composition of the ash is analyzed with X-ray diffraction. The fusibility of coal ash temperature is measured for the ash with the different CaO content. The results shows that fusibility of coal ash drops with the increasing CaO content until it reaches 3.0%; then it increases with the increasing CaO content.
