Coarse sand = diameter 2-0.2mm Fine sand = diameter 0.2-0.02mm Silt = diameter 0.02-0.002mm Clay = diameter less than 0.002mm. Note how the clay particles are much smaller than the sand particles – this is important as it means the total surface area of a clay soil is much greater and so the capacity to hold water is also much greater.
Types of Sand
Followings are the classification of Sand: Based on the grain size of the particle, sand is classified as Fine Sand(0.075 to 0.425mm), Medium Sand(0.425 to 2mm), and Coarse Sand(2.0 mm to 4.75mm)
Pit sand is a coarse type of sand and is normally found approximately 2-3 meters underground. This type of sand is obtained naturally when deep-enough pits are dug on the earth's surface. The resulting grains are usually sharp, angular, rough, and coarse. These features enable the sand to make strong bonds on surfaces.
Coarse Washed River Sand as the name suggests is the coarse version of the Washed River Sands. This sand contains small stones that gives it a coarse property. Coarse Washed River Sand is mainly used as bedding and concrete that doesn't require a clean finish.
The most commonly available gritty or coarse sand is builders sand because it's a common building material. It's used in concrete mixes and some mortar mixes. Builders sand is not the same thing as play sand or sandbox sand, which are made of finer, rounder grains, similar to beach sand.
Sand is commonly divided into five sub-categories based on size: very fine sand (1/16 - 1/8 mm), 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).

Fine river sand feels quite like washed sand, while coarse river sand has a fine, yet pebbly, feel. Generally both will be darker than sharp or washed sand and they have a very mixed particle size. Coarse river sand is used as a paving base.
River Sand is a great soil amendment for gardening and landscaping as it helps relieve clay soils from becoming compacted, and improves water and air infiltration. It can be mixed in with the soil or used alone like in a sand-based sport field or french drain.
Washed sand The 'washed' refers to the process by which clay, silt and dust are removed from the sand before it is left to drain. Washed sand refers to the process, so it can come in a range of grittiness and have a range of uses.

What is sharp sand? Also known as 'grit sand' or 'concrete sand', washed sharp sand is more coarse and has larger particles than other construction sands such as builder's sand, which consists of finer grains. Having a larger grain size than other types of sand means sharp sand is slightly heavier.
Is play sand the same as coarse sand? Play sand is much finer than coarse sand. The sand crystals are much smaller, and as a result, tend to have rounded edges. This makes it safer to play with, softer to touch, and better at sticking together when wet.
