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) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.

Sand + Silt Layer Height or Thickness = 10 cm. Silt Content of Sand = (1 cm / 10 cm) x 100 %. Silt Content of Sand = 1%. So, from the above Test and calculations, we can say that this sand has a 1% silt content. Silt content limit in sand as per IS code is 8%, so this sand we can use for construction purposes.

Hint: Sieving allows the fine flour particles to pass through the holes of the sieve while the bigger particles or impurities remain on the sieve. For example, in a flour mill, impurities like husk and stones are removed from wheat before grinding it. Complete answer: Sieving is a simple technique for separating particles of different sizes.

Sand is known as "argillaceous," "siliceous," or "calcareous;'' according to its composition.. It is procured from pits, shores of rivers, sea-shores, or by grinding sandstones.. It is chiefly used for mortar concrete and plaster.The qualities it should possess for those purposes are pointed out at page 198..

But sometimes in construction site required a special sieve machine and concrete mixer machine that are comfortable and easy use. Generally while preparing the mortar for construction purpose, the process of sieving of sand and mixing it with cement and water is carried out separately. These processes are carried out manually.

Classification of Sand: According to the size of grains, the sand is classified as fine, coarse and gravelly. ADVERTISEMENTS: The sand passing through a screen with clear openings of 1.5875 mm is known as the fine sand. It is mainly used for plastering. The sand passing through a screen with clear openings of 3.175 mm is known as the coarse sand.

Joint sand provides vertical interlock and shear transfer of loads. It can be slightly finer than the bedding sand. Gradation for this material can have a maximum 100% passing the 1.25 mm sieve and more than 10% passing the 80µm sieve. Commonly the bedding sand is used for the joint sand for easier control of job site materials.
