Transportation of fly ash is a major problem in its efficient disposal. The main problem associated with fly ash transportation is that the particles settle down sooner than desired. The primary objective of this research is that not only the fly ash particles should remain floated till it reaches the end but also settle down after that. In this investigation the role of a drag-reducing cationi...

Tremendous quantities of reservoir deposited sediments are required to be dredged regularly to maintain the storage capacity of the reservoir. The reservoir dredged material (RDM) can be utilized as construction material after admixing with additives such as cement and fly ash thereby improving its strength characteristics. This research paper presents results of laboratory investigation carrie...

This paper presents an Effect of Fly Ash on Properties of Concrete. In the present study. Use of fly ash in concrete imparts several environmental benefits and thus it is ecofriendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement. Fly ash is pozzolanic material & it improving the properties of co...

Removal of fly ash using wet scrubbers is widely used in the small and medium scale industries. Among the wet scrubbing methods, spray column falls into the simplest type category for its simple construction and various advantages. A novel pilot plant wet scrubber has been conceived, designed and fabricated. This paper distinctly focuses on the detailed design and fabrication of the ejector, wh...

To explore the agronomic potential of an Australian coal fly ash, we conducted two glasshouse experiments in which we measured chlorophyll fluorescence, CO2 assimilation (A), transpiration, stomatal conductance, biomass accumulation, seed yield, and elemental uptake for canola (Brassica napus) grown on soil amended with an alkaline fly ash. In Experiment 1, application of up to 25 Mg/ha of fly ...

Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...

Application of bio-fuel by-product sugarcane bagasse ash SBA as. Including sugarcane bagasse ash SBA13, recycled paper mill waste4.as bagassios. In this paper, Bagasse ash can be utilized by replacing it with fly ash and lime in fly ash bricks. Trial bricks of size 230x100x75 mm were tested.bagasse ash SCBA, several trials were conducted to define optimum burning time and temperatures. SCBA use...

Introduction Fly ash, a by-product from power plants, is a powdery gray material that is stored in large ash dykes or ponds. This ash is used in making bricks and in cement factories. Fly ash is considered to be a major pollution problem as it is dispersed into the air and pollutes bodies of water. However, for the local tribal populations of Korba district, Chhattisgarh state, fly ash is becom...

Class C fly ash is a coal combustion product normally produced from lignite or subbituminous coal obtained as a result of the power generation process. In recent years, efforts were taken to incorporate self-cementing fly ash into full-depth reclaimed (FDR) asphalt pavements to improve the structural capacity of asphalt pavement base layers. In this study, an existing asphalt pavement in County...
