What is Fineness Modulus of Sand Fine Aggregate and

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
