Fineness Modulus of Fine Aggregate The sand fineness module fine aggregate is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm,

Types Of Aggregates Difference Between Coarse and fine

Types Of Aggregates Difference Between Coarse And Fine

Fine aggregates comprise of natural sand and stone which are graded into Zone 1 to Zone 4 depending on its ability to move through the 600-micron. The zones become gradually finer from Zone-1 to Zone-4. As per zones, 90 to 100 of the fine aggregate moves through 4.75 mm IS sieve and 0 to 15 moves through 150 microns IS sieve.
