Sand is a very important building material for house construction after cement and steel. Sand is an ingredient in concrete, which makes up the basic structure of your house. Concrete is formed by mixing appropriate quantities of cement, sand, aggregates and water. Besides the use in concrete, sand is majorly used in brickwork and plastering. Most of us have seen masons mixing sand along with cement and water, and throwing applying the mixture (also called plaster) on the walls. It is then smoothened with trowels to give a clean texture. Since both plastering and concreting consume a lot of sand, knowing the right price is very important while buying it. A little-overpriced sand can cost you a lot of extra money, messing up your budget. You also have to decide which type of sand you are going to use in your house construction. Your decision can be influenced by the local availability of different types of sands.
Sand can be broadly classified into four types based on their source:
It is obtained from deep sand pockets beneath the ground. Generally, it is reddish-orange in colour.
It is extracted from river banks and sometimes from the river beds if the river is dry. It is very fine in quality and has white-grey colour.
Manufactured Sand or M-Sand:
It is manufactured by proper grinding and crushing of aggregates and stones into finer material.
It is obtained from seashores and is unfit for construction activities due to its salty nature.
Here are some most common types of sand used in Delhi NCR for construction:
Jamuna Sand (River Sand)
It is a colloquial term used for the sand extracted from the beds of Yamuna River. It is whitish and fine in nature. Some time back the government had put a ban on extracting sand from Yamuna River due to its negative effects on the natural ecosystem of Yamuna. It has low quality as compared to other sand types, and price ranges from ₹28-₹30 per cubic-feet. It is cheap because of its abundant natural availability. Although banned, some illegal extraction still happens in the river.
Badarpur Sand (Pit Sand)
It is a common term used for sand extracted from deep sand pits located in the region nearby Aravalli hills in Delhi and Haryana. It is red in colour and is extracted from very deep underground sources (sometimes even at the level of water table). It is very costly and not easily available. It is a little coarse in nature, just the right size for construction use.
Crusher dust (M-Sand)
It is obtained by crushing stones and aggregates to form stone dust. Due to the ban on extraction of Jamuna sand and high price and availability issues of Badarpur sand, this has been the most sought after alternative and widely used these days. Its price ranges between ₹32-₹35 per cubic-feet. It is blueish or reddish in colour depending on the colour of the parent rock from which it is obtained.
