Gradation of fine aggregate by sieve analysis

Jul 20, 2018· Gradation of aggregates is determined from sieve analysis, in which a representative sample of aggregate is passed through a series of sieves in top to bottom and the weight retained in each sieve – expressed as a percentage of the sample weight – is compared with the grading limits specified.by this test we calculate finesse modulus of our ...

What Is Grading Of Aggregates? And Its Limits [Civil Planets]

The aggregates are graded as per IS code 383, when the aggregate size is less than 4.75mm is called fine aggregate & more than 4.75mm is called coarse aggregate. The aggregate gradation is determined by the fineness modulus method where aggregates are passing through the sieve as per IS standard to classify its size.
