    Gradation of fine aggregate by sieve analysis

    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 aggregate that define as summing the cumulative percentage .
