Jul 20, 2021 · Calculation Process Concrete workers calculate fineness modulus using sieves with progressively smaller holes. Separate sets of sieves are used for coarse and fine aggregates. The measuring process itself will be the same for both categories of aggregate. First, the sieves must be arranged in a stack in descending order.
Get Pricethe coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subdivided by 100 gives the value of coarse aggregate. Higher the aggregate size higher the Fineness modulus hence fineness modulus of coarse aggregate is higher than fine
