How to check the standard for the uses of sand for construction

Why it is important to assess the standard for the uses of sand for construction?

Sand provides bulk, strength, and alternative properties to construction materials like asphalt and concrete. it’s additionally used as an ornamental material in landscaping as well. So sand plays a strong role for every construction work so we should access the standard for the uses of sand for construction.

Sand is a particularly requisite material for the development however this vital material should be purchased with all care and vigilance.

Assessing the quality of sand is a great idea to ensure the best construction. Sand is said to have a great impact on the strength of the construction. The building could develop cracks or damages with the use of improper quality of sand.


Based on the size of the particles, 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). The particles of fine sand are much smaller when compared to the other types. However, each of them has its own purpose in construction. Coarse sand is used for constructing pillars and underground tanks, while medium sand is used for the first layer of plastering and other works. The final finish of plastering includes the use of fine sand.

There are different standards for construction that must be checked and considered for better construction. The requirement of particle size of sand, according to which sand is chosen should be like:

  1. For plastering purpose, fine sand must not be less than 1.5
  2. For brick work fine sand used should not be but 1.2 to 1.5
  3. Concreting work require coarse sand in modulus of 2.5 to 3.5
  4. For all these purposes, the silt content should be more than 4 %.


Like any different material, their area unit bound options that confirm the standard of sand.

  1. Good quality sand should not possess more than 4% of silt content.
