1. What is sand?
Sand are inert particle materials that pass through the sieve of 4.75mm and retained on sieve size 63μm (0.063mm).
Sand is widely used in the construction industry mostly in the manufacture of concrete
2. Definiation of Sieve analysis test of sand
This is a test performed on sand to determine the percentage of different particle sizes contained within the sand sample.
3. Test method
• The test method used is dry sieve analysis.
