Mercury Transportation in Soil Using Gypsum from Flue Gas Desulphurization Unit in Coal-Fired Power Plant
… investigates mercury flux in soil amended by gypsum from flue gas desulphurization (FGD) units of coal-fired power plants. There are two phases of this research, including field and greenhouse studies. Previous studies indicate that FGD gypsum could increase corn yield, but may lead to more …

Impact of Surface Application of Flue Gas Desulfurization Gypusum on Infiltration, Phophorus Behavior, and Total Sulfur in a Previously Manured Coastal Plain Soil
Flue gas desulfurization (FGD) gypsum was surface-applied on a poorly drained cultivated Coastal Plain soil in Maryland containing excessive amounts of plant-available phosphorus (P). Using a constant head double-ring infiltrometer, a field experiment indicated a slight increase in final …

Soft Soil Stabilisation Using a Novel Blended Cementitious Binder Produced From Waste Fly Ashes
… activation using flue gas desulphurisation (FGD) gypsum, for use in soft soil stabilisation. The effects of different binders produced from unary (WPSA), binary (WPSA and POFA) and ternary (WPSA, POFA and RHA) blended mixtures, along with ground and FGD gypsum activated ternary mixtures, on …

NEW APPROACHES FOR MITIGATING ENVIRONMENTAL CONCERNS ASSOCIATED WITH COAL AND COAL COMBUSTION PRODUCTS
… ash, bottom ash, and flue gas desulfurization (FGD) material. The Hg is transferred to these coal combustion products (CCPs) from its associated parent coal. These CCPs absorb a significant amount of the Hg released during the combustion process. With the EPA's recent emphasis on controlling the …

Characterizing and modeling the hydrologic properties of coal combustion by-products in landfills
… ash, and flue gas desulfurization product (FGD gypsum). This investigation focused on determination of the saturated and unsaturated hydraulic properties of fly ash and bottom ash to then be used in order to develop a 1-dimensional unsaturated flow model. Ash samples from a power plant as …

Characterisation and properties of alkali activated pozzolanic materials.
… fly and bottom ash, flue gas desulphurisation (FGD) gypsum. However, less than 25% of the total ash from power stations has found an industrial use mainly in cement and concrete industry. This creates a massive waste-disposal problem. Disposal of unused fly ash in open tips and ponds, for …
