Remediation of Abandoned Mines Using Coal Combustion By-products
… was to investigate the effectiveness of coal combustion by-products (CCBs) in encapsulation of pyrite to remediate AMD. To meet this objective, CCB-based grouts were tested for spread, slump, bleed, and strength. Pyrite was coated with grouts and laboratory tests were performed to evaluate the …

Characterizing and modeling the hydrologic properties of coal combustion by-products in landfills
Coal combustion byproducts (CCBs) disposed of in unlined landfills can impact the quality of adjacent water resources. In previous studies, CCBs have been found to leach toxic heavy metals such as arsenic, mercury, and lead into groundwater. CCBs include fly ash, bottom ash, and flue gas …

Computer simulations to calculate energy flux and image size on a receiver for different reflector geometries using caustics
… of fossil fuels and the toxic effects of combustion by products are all pushing towards the energy production via renewable energy sources. Most of the countries that lie on the ‘‘Sun Belt’’, where solar irradiation is sufficient, are working towards harvesting and exploiting solar energy. …

Experimental improvement of flyash as a growth medium for plants through addition of selected solid wastes
… of more than 15 Mt of ash and associated coal combustion by-products in 1987 alone. This poses a large scale waste-disposal problem. Flyash, the major waste product is from South African coal sources, an alkaline, saline material the pozzolanic nature of which results in the formation of …

Analysis of coal combustion by-product disposal practices in an arid climate : leachate water quality
Coal combustion by-products (CCBs), produced from a large power plant in New Mexico, have been disposed of in a nearby coal mine since 1973. These CCBs consist of fly ash, bottom ash, and sludge from the flue gas desulfurization process and have elevated concentrations of hazardous constituents. …

Non-traditional sources of critical minerals from the Western Canada Sedimentary Basin
… Basin (WCSB) with a focus on REE from coal combustion by-products (CCBs) and Li from basinal brines. The first phase of this work used machine learning to identify geochemical indicators of REE enrichment in sedimentary strata which can be used to predict where elevated abundances may be …

Performance and mechanism on a high durable silica alumina based cementitious material composed of coal refuse and coal combustion byproducts
<p>Coal refuse and combustion byproducts as industrial solid waste stockpiles have become great threats to the environment. Recycling is one practical solution to utilize this huge amount of solid waste through activation as substitute for ordinary Portland cement. The central goal of this …
