Sand is a naturally occurring granular material composed of finely divided rock and mineral particles.
"As the term is used by geologists, sand particles range in diameter from 0.0625 (or 1/16 mm) to 2 millimeters. An individual particle in this range size is termed a sand grain. The next smaller size class in geology is silt, particles smaller than 0.0625 mm down to 0.004 mm in diameter. The next larger size class above sand is gravel, with particles ranging from 2 mm up to 64 mm (see particle size for standards in use). Sand feels gritty when rubbed between the fingers (silt, by comparison, feels like flour). Sand is one of the common paving materials used in the mixture found in our roads."
"ISO 14688 grades sands as fine, medium and coarse which ranges from 0.063 mm to 0.2 mm to 0.63 mm to 2.0 mm, and is one of the many road materials used in pavement in Erie, PA. In USA, sand is commonly divided into five sub-categories based on size: very fine sand (1/16 - 1/8 mm diameter), fine sand (1/8 mm - 1/4 mm), medium sand (1/4 mm - 1/2 mm), coarse sand (1/2 mm - 1 mm), and very coarse sand (1 mm - 2 mm). These sizes are based on the F sediment size scale, where size in F = -log base 2 of size in mm. On this scale, for sand the value of F varies from -1 to +4, with the divisions between sub-categories at whole numbers."
"Gravel is crushed stone that is of a specific particle size range. In geology, gravel is any loose rock that is larger than two millimeters (2mm) in its largest dimension (about 1/12 of an inch) and no more than 63 millimeters (about 2.5 inches). Sometimes gravel is restricted to rock in the 2-4 millimeter range, with pebble being reserved for rock >4-63 millimeters. The next smaller size class in geology is sand, which is >0.063 mm to 2 mm in size. The next larger size is cobble, which is >63 millimeters to 256 millimeters (about 2.5 to ten inches). One cubic foot (28.32 dm3) of gravel typically weighs about 100 pounds (45 kg)."
"Gravel is an
important commercial product, used in many applications including
being used as driveway stone. Many roadways
are surfaced with gravel, especially in rural areas where there is
little traffic. Globally, far more roads are surfaced with
gravel than with concrete or tarmac; Russia alone has over 400,000
km of gravel-surfaced roads."
