Impoundment of Fly Ash and Slag: A Case Study

Design and Construction of Bituminous Fly Ash Disposal Sites

In Situ Testing of a Compacted Fly Ash Fill

New and Conventional Engineering Uses of Fly Ash
Successful uses of pozzolanic fly ash for modification of a highly plastic clay, and of natural and stabilized fly ashes to effect economy in road construction, are described. Three fly...

Fly Ash Pavements, Run Ways to Take Off—
Significant cost savings were realized in paving a new container terminal storage yard in Portland, Oregon. A computer analysis showed that a multi-layer pavement would be best, with each...

Evaluation of Synthetic Aggregate from Lignite Fly Ash
This paper deals with the burning of various combinations of pelletized fly ash, agglomeration agents, and additives to make a synthetic aggregate. Several methods of agglomerating and...

Field Consolidation of High Ash Papermill Sludge
Settlement and pore pressure measurements on a carefully constructed high ash papermill sludge landfill are presented. The landfill consisted of two sludge layers, each initially 10 ft...

Water Quality Management — Power Station Coal Ashes

Consolidation of High Ash Papermill Sludges
Experimental laboratory results for one-dimensional compression behavior of dewatered pulp and papermill sludges are presented. Data were obtained with a fixed-ring oedometer and a pressurized...

Disposal and Uses of Power Plant Ash in Urban Area
Increased coal fired generating capacity results in higher ash production. This is compounded by the increased ash content and lower Btu value of coal, and the installation of high efficiency...

Bottom Ash: An Engineering Material
The properties and uses of bottom ash, a by-product from burning coal in power plants, are discussed. Selected samples of bottom ash from the State of West Virginia and the surrounding...

Engineering Properties of Compacted Fly Ash
The lower compacted density of fly ash relative to conventional earthfill recommends its use when a fill or embankment must be constructed over soft, compressible ground. Field evidence...

Fly Ash as Structural Fill
Field and laboratory tests on fly ash from power plant disposal areas are presented with parameters for design and construction of fly ash embankments. Controlled compaction permits 20%...

Permeability of High Ash Papermill Sludge
Most deposits of high ash papermill clarifier sludges contain very high water contents, show little drainage over the years, are unstable, and are subject to large settlements under surface...

One Dimensional Lunar Ash Flow With And Without Heat Transfer

Recent Developments in Grouting for Deep Mines
Grout-impregnated columns can be used as a means of providing support for structures built over deep mined areas. The columns can be used to maximum advantage in areas of a mine which...

Properties of Compacted Sewage Ash
Properly compacted sewage ash from a local treatment plant exhibits sufficient strength and stability to recommend its use on a trial basis as a backfill, lightweight structural fill,...

Solidification of Sludges with Portland Cement
Raw primary sewage sludge and a chicken manure was solidified by mixing with fly ash and Portland cement. By varying the proportions of sludge solids, fly ash, and cement in a mix, it...

Rational Aspects of Spilt Treatment Lime Softening
Split treatment in lime-soda ash water softening is an old and well known process. However, it has been erroneously considered an outdated process since the development of recarbonation...
