Importance Of Sand In Construction

My dear readers I hope your week is going well so far, i have a little information i want to share with you today. Do you know that sand is an extremely needful material for building and construction? Although, this same important material must be purchased with all care and vigilance. Sand which is used in construction purpose must be clean, free from waste, stones and impurities.

It is also important to know what type of sand is beneficial for construction purposes, as sand is also classified into three different forms which makes it suitable for specific type of construction.

Sand is classified as: Fine Sand (0.075 to 0.425 mm), Medium Sand (0.425 to 2 mm) and Coarse Sand (2.0 to4.75 mm).

Here’s a description of the types of sand:

Pit Sand (Coarse sand)

Pit sand is classified under coarse sand which is also called badarpur in common language. This type of coarse sand is procured from deep pits of abundant supply and it is generally in red-orange colour. The coarse grain is sharp, angular and certainly free from salts etc which is mostly employed in concreting.


River Sand (Fine Sand)

River sand is procured from river streams and banks and it is fine in quality unlike pit sand. This type of sand has rounded grains generally in white-grey colour. River sand has many uses in the construction purpose such as plastering.

Sea Sand

As the name suggests, sea sand is taken from sea shores and it is generally in distinct brown colour with fine circular grains. Sea sand is avoided for the purpose of construction of concrete structure and in engineering techniques because it contains salt which tends to absorb moisture from the atmosphere and brings dampness. Cement also eventually loses its action when mixed with sea sand that is why it is only used for local purposes instead of structural construction.

There are different standards for the construction purposes which must be checked and considered for better construction. The requirement according to which sand is chosen should be like:
For plastering purpose: The overall fine sand used must not be less than 1.5 while silt is preferred not less than 4 percent.
For brick work: Fine sand used must not be less than 1.2 to 1.5 and silt is preferred at 4 percent generally.
Concreting work requires: Coarse sand in modulus of 2.5 to 3.5 with not less than 4 percent silt content.

I hope you have gained from this little information, do have a nice day.
