Geochemical partitioning from pulverized coal to fly ash and bottom ash
Fuel, 2020Abstract Fly ash and bottom ash chemistry is a function of the chemistry and mineral assemblages of the feed coal in addition to coal pulverization, boiler type and size, combustion parameters and combustion efficiency, and configuration of the ash collection system.

Chemical Speciation of Vanadium in Coal Bottom Ash
CLEAN – Soil, Air, Water, 2012AbstractChemical speciation of vanadium is important to understand the true nature of this element in the environment as well as its biochemical pathways. Sample pretreatment, preparation, and chemical speciation methods were applied for vanadium in coal bottom ash here.

REMOVAL OF POLLUTANTS FROM WASTEWATER BY COAL BOTTOM ASH
Journal of Environmental Science and Health, Part A, 2002Coal bottom ash produced from a thermal power plant was used in a batch experiment to investigate the adsorption characteristic of this bottom ash. The adsorbate solutions were synthetic wastewaters contained copper (Cu2+) or COD and a sanitary landfill leachate.

Coal Bottom Ash As a Concrete Ingredient: Review
SSRN Electronic Journal, 2019Coal bottom ash (CBA) generated from power plants have become a major environmental concern and hence its usage by recycling it is the increasing demand for research nowadays. CBA is collected from bottom of the boiler and is normally as coarse sand to fine gravel size material which is generally used as a low cost replacement material.

Coal bottom ash natural radioactivity in building materials
Journal of Radioanalytical and Nuclear Chemistry, 2018The viability of ground coal bottom ash as a potential Portland cement constituent to be used in building materials is assessed. Currently, coal fly ash is used to produce Portland cements and concretes. However, coal bottom ash is mainly landfilled. Gamma spectrometry analysis, compressive strength, physical and chemical testing were performed.

Experimental Study of Bottom Coal Ash-Geogrid Interaction
Geo-Congress 2014 Technical Papers, 2014About 40% of the electricity generated in the U.S. is from coal combustion power plants (US-EIA 2013). As a result, more than 130 million metric tons of coal combustion residuals (CCRs) are produced in the U.S. annually (ACAA 2011). Despite reutilization efforts, more than 70% of fly ash produced in the U.S. is disposed of in ash landfills (dry method)

Stabilization of black cotton soil with coal bottom ash
Materials Today: Proceedings, 2022Abstract Expansive soils are problematic due to the performances of their clay constituent usually have the potential to show their undesirable engineering properties such as low bearing capacity, high shrinkage and swell characteristics. The shrink-swell behaviour makes the soil inappropriate for direct engineering application in its natural form ...

High fire resistance in blocks containing coal combustion fly ashes and bottom ash
Waste Management, 2011Fire resistance recycled blocks, containing fly ash and bottom ash from coal combustion power plants with a high fire resistance, are studied in this paper by testing different compositions using Portland cement type II, sand, coarse aggregate and fly ash (up to 50% of total weight) and bottom ash (up to 30% of total weight).

Usage of coal combustion bottom ash in concrete mixture
Construction and Building Materials, 2008Abstract The present study aims to determine and evaluate the applicability of an industrial bottom ash (CBA), supplied from Tuncbilek Power Station-Turkey, in concrete industry. In the laboratory experiments, the bottom ash was used up to 25% as a partial substitute for the Portland cement.

Coal bottom ash as light fill material in construction
Waste Management, 1996In today's society, there are increasing requirements on recirculating wastes and residues to the greatest possible extent. Among the waste products with major potentials for recycling are ash and slag from energy production. The combination of interesting material properties and environmental acceptability makes these products suitable for application
