The swell factor of materials such as sand and gravel is a variable which is dependent upon the type and compaction of the undisturbed (bank run) material. Generally speaking swell for sand and gravel can range from 12% to 40%. The variability in swell is affected by moisture, clay and other mineral content. Clean, dry sand and gravel tends towards the 12% end with an average of around 17%. Swell increases to the right as the material tested becomes "dirtier".
Bank cubic yard (BCY) is converted to loose cubic yard (LCY) by multiplying the BCY x swell factor + BCY.
Swell of a given deposit can be approximated by the use of several calibrated buckets. Carefully excavate a volume of bank run material and place it directly into calibrated buckets of a known volume. (Note: a five gallon bucket in not a five gallon bucket, you need to actually calculate the volume.) Before moving the filled or partially filled buckets, measure the depth from the rim top to the average top of material and also weigh each bucket. Carefully record the numbers for each bucket. Next, carefully measure and calculate the volume of the hole from which the material was removed.
The volume of material in the buckets (loose) will be larger than the volume removed from the hole (bank). The difference reflects the amount of swell for that particular deposit.

Why use sand in concrete?
The sand (ballast) provides strength, hardness, and durability. The cement binds the sand/gravel together.
What method do you use in sand and gravel?
In sand and gravel mining, various methods are used including mechanical dredging, hydraulic dredging, and open-pit mining. These methods involve extracting the sand and gravel from the earth either underwater or from open pits, and then processing and sorting the material for commercial use. Environmental regulations and sustainability practices are important considerations in sand and gravel mining.
