Mobile Pilot Plant to Reuse Fly Ash in Concrete
Influence of Particle Structure on Properties of Fly Ash and Sand
Three Case Histories of Waste Stabilization
Subsurface Characterization and Design of an Ash Landfill on Varved Clays
Fly Ash Grouts for Subsidence Control
A laboratory investigation was undertaken to examine procedures for evaluating candidate grouts and to develop quality grouts for use in abandoned mines. The objective of this grout application...
Properties and Environmental Impact of Stabilized Fly Ash
This paper summarizes the results of two research studies aimed at evaluating the properties and possible environmental effects of bituminous and lignite coal based fly ashes stabilized...
Stabilized Fly Ash Cover for a Municipal Waste Landfill
The study reported herein and several recently related projects have been aimed at reducing the hydraulic conductivity of fly ash and physiochemically fixing any potential leachable metals....
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Raising of an Ash Disposal Pond by Hydraulic Filling
Commercial and industrial development around existing power plant waste disposal sites often precludes the ability to expand these sites laterally. Limitations on land availability have...
Acid Mine Drainage Control Utilizing Fly Ash
Acid mine drainage is a serious environmental problem confronting the Appalachian region. Fly ash, the air particulate residual from the combustion of coal, is also an environmental concern...
Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...
Fly Ash in Roller Compacted Concrete Pavement
This paper presents the state of practice on the use of fly ash in roller compacted concrete (RCC) pavements. Placed using asphalt pavers and compacted using asphalt rollers, RCC pavement...
Superplasticized High-Volume Fly Ash Structural Concrete
This research was carried out to develop structural grade concrete containing high-volumes of ASTM Class C fly ash. A Portland cement concrete, proportioned to have 28-day compressive...
Use of Stabilized Fly Ash for Seepage Control
Evaluation of Waste Fly Ash Pretreatment Process
A batch acid-leaching pretreatment process was investigated for its potential to reduce toxicity and leachability of a municipal waste combustor fly ash prior to land disposal. Elemental...
Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...
Fly Ash for Hire
Each year, roughly 15 million tons of ash created by U.S. coal-fired powerplants is recycled. Most is used in concrete and other construction materials, such as structural fill, but utilities,...
Oilcrete
Threatened by probable tightening of hazardous-waste legislation, oil companies are searching for ways to dispose of or stabilize oil-drilling byproducts. One way is cementitious stabilization...
