characteristics of fly ash produced at power and water desalination plants firing fuel oil
plants firing fuel oil produce huge quantities of fly ash as solid waste, which needs to becharacterized prior to its proper management. it is worth mentioning that the published literature lackcomprehensive information on the characteristics of such fly ash. characteristics of fuel oil fly ash producedat selected power (pp) and water desalination (dp) plants were determined. the results showed...
متن کاملRheology and setting of high volume fly ash mixtures
While high volume fly ash (HVFA) concretes can be designed and produced to meet 28-d strength requirements and often even exceed the durability performance of conventional concretes, a persistent problem is the potentially long delay in setting time that produces concurrently long delays in finishing the concrete in the field. Previous isothermal calorimetry studies on two different powder addi...
متن کاملOn the Radioactivity of Fly Ashes from Coal Power Plants
The radioactivity of Greek lignites and their ashes was studied. It was found that the radionuclides in them belong to the uranium series. Fly ashes are relatively rich in radioactivity. Concentrations up to 7 , 1 0 _ 5 g / g and 12 pCi/g were measured for 238U and 226Ra, respectively. The associated hazards from radioactivity escaping from stacks of thermopower plants or when fly ashes are use...

متن کاملRadioactivity of Coals and Fly Ashes
Coal, like most materials found in nature, contain trace quantities of the naturally occurring primordial radionuclides. Therefore, the combustion of coals results in the release into the environment of some natural radioactive elements and in a redistribution of these radioactive elements in the surface soil particularly in the vicinity of coal-fired power plants, where it can modify ambient r...
