What does fly ash weigh per cubic foot? - Answers

Oct 01, 2009· The weight of fly ash per cubic foot is based on the specific gravity of the particular fly ash multiplied by the weight of water (62.4 lbs.) per cubic foot. Most fly ash has a specific gravity between 2.15 and 2.30, depending on the source. To calculate the weight per cubic foot of fly ash with a specific gravity of 2.3, the formula is as follows: 2.3 X 62.4 = 143.52 lbs per cubic foot
