FINE AGGREGATE:-

•  Aggregate most which passes 4.75mm sieve.

 TYPE OF FINE AGGREGATE:- 

•  NATURAL SAND -Fine aggregate resulting from the natural disintegration of rock and which has been deposited by streams or glacial agencies. 
•  CRUSHED STONE SAND -Fine aggregate produced by crushing hard stone. 
•  CRUSHED GRAVEL SAND - Fine aggregate produced by crushing natural gravel. 
•  MIXED SAND -Fine aggregate produced by blending natural sand and crushed stone sand or crushed gravel sand in suitable proportions. 
•  MANUFACTURED SAND -Fine aggregate manufactured from other than natural sources, by processing materials, using thermal or other processes such as separation, washing, crushing and scrubbing.

      NOTES

• 1 For crushed stone sands, the permissible limit on 150 micron IS Sieve is increased to 20 percent. This does not affect the 5 percent allowance permitted,

PROCEDURE :-

1. Taken sample 1000 gms of fine aggregates.
2. Arrange the sieve set from top to bottom as follows 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron, 150 micron, and Pan.
3. After weighing the sample, transfer the sample to 10 mm sieve and cover it with lid.
4. Place the assembly of sieve set on mechanical sieve shaker and sieve it for five to ten minutes.
5. Remove the assembly from mechanical sieve shaker and weigh the sample retained on each sieve, simultaneously note down in observation sheet.
