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

It varies based on the density of the mix, but should be around 145 lbs per cubic foot. 27cu ft/cu yd -> 27 x 145 = 3915 pounds per cubic yard
If the fly ash has not been compacted, the mass will be between 900 and 1500 pounds. If it has been compacted then the mass per cubic yard will increase to between 1900 and 2500 pounds.
The density of fly ash can vary depending on factors such as its particle size and composition, but it typically ranges from 1.9 to 2.4 grams per cubic centimeter.
The cost of fly ash per metric ton can vary depending on factors such as location, supplier, and quantity purchased. On average, the cost of fly ash ranges from $20 to $50 per metric ton. It is recommended to contact local suppliers for current pricing information.
Concrete is made out of sand, ash, and limestone. Sand provides the bulk of the material, ash or fly ash acts as a binder, and limestone is used as a filler to enhance the properties of the concrete.
Ash is a fine, powdery residue left after combustion. It is usually light grey in color and can vary in texture from gritty to smooth, depending on the source material. Ash is typically non-toxic and has a high pH level.
Volcanic ash can damage aircraft engines by melting and solidifying on internal parts, leading to engine failure. The ash can also cause visibility issues and damage aircraft structure due to abrasion. As a result, it is unsafe for planes to fly through areas with volcanic ash.
