River sand is found in river streams and banks and is fine in quality, unlike pit sand. This type of sand has rounded grains generally white-grey in color. River sand is used for brick-work and plastering during construction.

Description

 River Sand is used as a fine aggregate in mortars and concrete. Natural river sand is the most preferred choice as a fine aggregate material. … We can supply river sand (coarse / fines) for construction (suitable for building, plastering, and ready-mix concrete. About 35 % volume of concrete is comprised of sand. Generally, cement and coarse aggregates are factory-made products and their quality and standards can be easily controlled and maintained. The sand is usually excavated from river beds or a river bank by digging. The natural sand deposits are getting depleted by continuous digging causing damage to the environment in many ways. As the supply of suitable natural sand near the point of consumption is becoming exhausted, the shortage of good natural sand for concrete production is facing challenges.

Advantages of Natural Sand:

 It is naturally available and extracted from the river banks or river beds.

– The shape of natural sand is rounded and has a smooth surface.

– Moisture is generally present in between the particles. Hence, effects the assumptions of concrete mix design and quality of concrete.

– The compressive strength, as well as the flexural strength of concrete made from natural sand, are lower than Crushed sand.

– It contains silt as river water contains it due to the erosion of soil in its catchment area. Hence it needs washing on site.

– Oversized materials are expected in natural sand and hence need screening on site.

– It may contain marine products such as grass, algae, clay lumps, bones, shells, mica, etc. which are harmful to properties of concrete.

– It is harmful to the environment. It reduces the groundwater level and rivers water gets dried up.

– It has a high probability of adulteration because of acute shortage. River sand adulteration with saline sea sand is common in coastal areas.

– It is recommended for RCC, plastering and Brick/Block works

– The quality of natural sand deferrers though they may be from the same river bed.

– Mostly conforms to zone II and zone III

– The presence of silt and clay in the sand reduces the setting time of cement and make concrete and mortar weak and holds the dampness.

– The requirement for cement is more.

– Water table level gets reduced due to dragging of the sand from the river and the roots of the tree may not be able to get water.

– In the absence of sand in the river, water gets evaporated due to direct sunlight.

– The slump is more.
