Specific Gravity. Specific gravity values of the MSWI ash in the literature suggest values ranging between 1.5 and 2.5. Specific gravity values of the MSWI ash tested as part of this study suggest values ranging between 2.1 and 2.6. These relatively low values, suggest that the MSWI ash could be used as lightweight fill.

Fly Ash. Fly Ash is a byproduct of coal-fired electric generating plants. The coal is pulverized and blown into burning chambers for immediate combustion. Heavier ash particles (bottom ash or slag) fall to the bottom of the burning chamber and the lighter ash particles (Fly Ash) fly out with the exhaust gas, thus the term Fly Ash.
