CHAPTER 2 SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly
PDF | To find fineness modulus we need to perform sieve analysis and for that above mentioned sieve sizes, mechanical shaker and digital weigh scale are required Theory Fineness modulus of coarse .
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 of sieves, and dividing the sum by 100

FINENESS MODULUS The fineness modulus is an indicator of the fineness of an aggregate and is most used for evaluating fine aggregat The higher the number, the coarser the aggregate The fineness modulus is computed by adding the cumulative ,
Sieve AnalysisAs we know that the Fineness modulus is a measurement of the coarseness or fineness of a given aggregate, higher the FM the coarser the aggregate The above table is showing us that the Laurence pure sand is coarser then Chenab sand ,

Ravindra K Dhir OBE, , Chao Qun Lye, in Sustainable Construction Materials: Copper Slag, 2017 343 Fineness Modulus The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mix The higher the value of FM, the coarser the aggregate Generally, a lower FM results in more paste, making the concrete easier to finish
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 of sieves, and dividing the sum by 100 The sieve sizes are 015 mm, 03 mm, 06 mm, 118 mm, 236 mm, 475 mm, 95 mm, 190 mm, 381 mm and larger increasing in the ratio of 2:1
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.
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 siev The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness .
Fineness Modulus is a term used as an index to the fineness or coarseness of aggregate This is the summation of cumulative percentage of materials retained on the standard sieves divided by 100 It is well–known that aggregate plays an important role in achieving the desired properties of concrete Though, aggregate constitute 80 to 90% of .
