Fly Ash as a Potential Waste Liner
Earthen liners have been widely used to contain toxic and hazardous materials in ponds and landfills. There is close scrutiny over the durability of liners in contact with various wastes...
Stabilization of FGC Wastes
Presently, flue gas cleaning (FGC) wastes (scrubber sludges and flyash) are produced in large quantities, with future production likely to increase as utilities install additional stack...
Dynamic Shear Modulus of Flyash
Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
An Analysis of the Economic Post-Combustin Recovery Potential for Selected Metals at Municipal Incinerator Facilities
The Typical Engineering Properties of Fly Ash
Knowledge of key physical and engineering properties of coal fly ash is needed in the planning, design, and construction of both disposal and utilization projects. While considerable data...
Fixation of Chromium and Cadmium from Electroplating Waste Sludges
The authors compare the effectiveness of two fixation techniques, namely silicate-cement and lime-fly ash, for immobilizing chromium and cadmium in a waste sludge obtained from an electroplating...
Unique Ash Disposal Facility Protects Water Quality
Fly Ash Disposal and Groundwater Quality
Coal Ash Disposal and Water Quality: A Case Study
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
Need a Dependable Backfill—Try a Flowable Fly Ash
Flowable fly ash is a relatively new cementitious structural backfill material. It can be used in water or in the dry and will flow into place without the usual labor-intensive activities...
Water Quality Issues at Fossil Fuel Plants
This publication highlights proposed approaches and actual projects for dealing with such water quality issues at fossil power plants as water supply, water treatment, and the protection...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Low Cement Content High Strength Concrete
The fundamental objective of this research project was to develop mix design information for structural grade concrete using high fly ash content. The fly ash used in this project was...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
Decision Analysis of Coal Ash Disposal Technology
Coal-fired power plants produce a number of solid waste streams in the course of their operation. These coal combustion by-products (CCBPs) are composed of fly ash, bottom ash and boiler...
