Fineness modulus also provides important information about the density of the resulting concrete as well as its compressive strength Both of these factors must be taken into consideration when designing the concrete For more information about the role played by fineness modulus contact the concrete experts at Southport Concrete Corp

13 ensp 0183 ensp Fineness Modulus FM The results of aggregate sieve analysis is expressed by a number called Fineness Modulus Obtained by adding the sum of the cumulative percentages by mass of a sample aggregate retained on each of a specified series of sieves and dividing the sum by 100 The following limits may be taken as guidance

5 ensp 0183 ensp Limits of Fineness Modulus Fineness modulus of coarse aggregate varies from 5 5 to 8 0 And for all in aggregates or combined aggregates fineness modulus varies from 3 5 to 6 5 Range of fineness modulus for aggregate of different maximum sized aggregates is given below

1 ensp 0183 ensp Fineness Modulus FM A single number system used to express the fineness or coarseness of an aggregate Higher values indicate coarser grading Sum of cumulative retained on the standard sieves Certain sieves are NOT counted even if used Can be helpful in

Fineness modulus Wikipedia The Fineness modulus FM is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series

To find the fineness modulus of fine aggregate we need sieve sizes of 4 75mm 2 36mm 1 18mm 0 6mm 0 3mm and 0 15mm Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate Determination of Fineness Modulus of Sand To determine the fineness modulus we need standard sieves mechanical sieve shaker optional
