Medium sand: fineness modulus is 30-23 the average particle size is 05-035 mm fine sand: fineness modulus is 22-16 the average particle diameter is 035-025 mm extra fine sand: fineness modulus is 15-07 and the average particle diameter is less
The fineness of the sand plays an important role in the finishability of the concrete mix and even small changes in fineness can affect finishing the fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading it is defined as the summation of the cumulative percent retained
Title: concrete mix design- a modification of the fineness modulus method author(s): myron a swayze and ernst gruenwald publication: journal proceedings volume: 43 issue: 3 appears on pages(s): 829-843 keywords: none date: 311947 abstract: a comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of

B) as per the grading given in table 1 the fineness modulus of sand could vary from i2 to 22 however it is preferable to have minimum fineness modulus of l-4 in case of crushed stone sands and crushed gravel sands and a f m of 1 5 in case of naturally occurring sands hence
As fineness modulus of sand changes from 25 there is an increase in compressive strength from 43on the other hand by increasing fineness modulus from 25 to 3 compressive strength increases from 49 due to over consumption of natural river sand deposits creating several environmental issues as an alternatekolkata fineness modulus of

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
