How Fine Aggregate Affects Mix Design of Concrete?
Fineness Modulus. It is one of the factors that influence concrete mix design since it controls the proportion of sand in concrete mixture. The overall fineness of sand is given by factor called fineness modulus, and it is found by sieve analysis based on ASTM C 33/ M33 specifications or any other applicable standards. The fineness modulus of ...

Fineness Modulus of Sand (Fine Aggregates)
What Is Fineness Modulus of Sand? Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
