Fly ash contains the radiochemical polluting elements of the U and Th series, along with other radioactive contaminants like 222 Ru and 220 Ru. Bhangare et al. (2014) measured the radioactivity of 238 U, 226 Ra, 232 Th and 40 K for fly ash from six power plants across India. All the samples were found enriched with the radionuclides.

Mar 15, 2019· It was further found that low-Ca class F fly ash was the most suitable to obtain zeolite Na-P1 crystals. Alternatively, high-Ca class C fly ash promoted the synthesis of hydroxysodalite and calcite. Higher porosity (52%) and surface area (99.5 m 2 /g) were achieved for the geopolymer-supported zeolites. These materials can be potentially used ...
The most-often-used specifications for fly ash are ASTM C 618 and AASHTO M 295.Two major classes of fly ash are specified in ASTM C 618 on the basis of their chemical composition resulting from the type of coal burned; these are designated Class F and Class C. Class F is fly ash normally 47 JOURNAL Of NUCLEAR And Related TECHNOLOGIES, Volume 4 ...
Ca levels of fly ash from co-combustion of wood with coal were lower than those of fly ash coming from the combustion of wood solely. - When the proportion of wood in the coal/wood mixture is increased, the concentration of alkalis (Na and especially K) is also elevated.
