WebThe main goal of research presented in this paper was the material and radiological characterization of high volume fly ash concrete (HVFAC) in terms of determination of natural radionuclide content and radon emanation and exhalation coefficients. WebApr 10, 2016 · The pH value of fly ash is 12.15 because of its alkaline nature. The EC value of fly ash is 57.68 mS/cm, which is 287 times higher than for the soil used in Taghipour and Jalali [ 40 ]. This demonstrates that a large amount of soluble salt exists in fly ash and thus increases the difficulty in immobilization. Table 2 Properties of fly ash. Figure 4

WebThe radioactivity comes from the trace amounts of uranium and thorium contained in coal. These elements have been trapped in the Earth’s crust since its formation and are usually in concentrations too low to pose any serious threat. But the burning of coal produces fly ash, a material in which the uranium and thorium are much more concentrated. Fly ash is a light colored, fine particle waste that resembles a powder. The majority of coal combustion wastes are fly ash. Bottom ash is a larger particle size then fly ash and is a heavier waste that resembles a mix of sand and small rocks. Just over 10% of coal combustion waste is bottom ash.
