... afforded by additives such as fly ash and organoclays. The objective of this study is to examine the sorption levels of naphthalene to several cement-treated soil mixtures with and without organic additives (i.e., fly ash and organoclay) using batch testing. It is found that the sorption values...

... The aim of this study was to determine the possibility of using fly ash for the solidification/stabilization (S/S) of Ni and Zn contaminated sediment from the Krivaja river basin (Serbia), which represents an extraordinary risk to the environment and belongs to the last quality class...

... The objective of the research was to determine if fly ash not meeting ASTM C618 can be used successfully in an aggregate-lime fly ash-stabilized base course (ALFASB). The Tennessee Dept. of Transportation (TDOT) Specification 312 for ALFASB includes hydrated lime, fly ash, and TDOT grading C...

... of properly screened LKD to act as a mineral filler, and the presence of fly ash in the dust that provides potential pozzolans for applications where strength is important. This paper explores the important properties of lime kiln dust and how these properties can be used in a variety of applications...

... is a function of the bentonite content of the foundry sand, to general, as the bentonite content of the foundry sand increases, the water content of the mixture should increase correspondingly. The amount of fly ash has only a modest effect on the amount of water required. The most important factor affecting...

... Mine stabilization with coal combustion by-products such as fly ash is common throughout the United States. However, the use of the dry scrubber ash as opposed to fly ash has created some unique challenges in permitting and monitoring. The dry scrubber ash is a mixture of fly ash and residue...

... with Type F fly ash. Our work also examined the susceptibility of these materials to frost heave and thaw weakening. An apparatus and standard test method for performing permeability during freezing and after subsequent thawing did not exist. We developed a method by adapting the ASTM Standard Test Method...

... in fly ash modified mortars and stuccos, and specifications have been written that limit the amount of fly ash that can be added to a mortar. By combining expertise in masonry with expertise in pozzolans, we have worked with masons and plasterers to develop a line of high-pozzolan masonry cements, mortar...

... Deterioration of concrete structures due to reinforcement corrosion because of chloride ingress is a growing problem in many countries throughout the world. Partial replacement of portland cement by mineral additions, such as ground granulated blast furnace (GGBS), silica fume and fly ash...

... Little Scary Creek (LSC), a 2nd-order tributary of the Kanawha River in West Virginia, receives treated fly ash produced during coal combustion. Selenium and other trace metals were determined in water column and sediment samples, caddisflies, and bluegill sunfish liver and gonads during 1995–96...

... A controlled low-strength material (CLSM) has been successfully used in two microtunneling applications. This CLSM, developed at the U.S. Army Engineer Waterways Experiment Station (WES), is a mixture of ASTM Class C fly ash, ASTM Type I portland cement, bentonite, and water. The CLSM was first...

... The use of asphalt emulsion with hot lime slurry in cold in-place recycled (CIR) mixtures was evaluated as an alternative to the use of conventional asphalt emulsions (AE) or class C fly ash. Reclaimed asphalt pavement was mixed with 1.5% AE, 8% and 12% class C fly ash, 1.5% AE with 1.5...

... A laboratory study is described in which the engineering properties of subgrade soils were modified by treatment with fly ash derived from low-sulfur western coal. A wide range of soil types including gravel-sand, silty sand, sandy silt, and highly plastic clay exhibited substantial improvements...

... An investigation was made to study the suitability of using coal fly ash-stabilized sand mixtures as capping materials for sanitary landfills. Sand mixtures stabilized with 15 and 20 percent Class C fly ash were investigated. Compaction, permeability, unconfined compressive strength, freeze-thaw...
