Oct 14, 2016 Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.50 to 8.00. Combinations of fine and coarse aggregates have intermediate values. The thickness of fine aggregate is divided into 4 levels according to fineness modulus.
To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm.

Fine aggregate means the aggregate which passes through 4.75mm sieve. 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.

Jan 01, 1994 Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample. FM is the sum of the total percentages retained on each specified sieve divided by 100. ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM, the coarser the aggregate.
aggregate have openings ranging from 150 m to 9.5 mm (No. 100 sieve to . 3 8. in.). The 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. to 4 in.). Tolerances for the dimensions of open-ings in sieves are listed in ASTM E 11 (AASHTO M 92). Size numbers (grading sizes) for coarse aggregates
Apr 11, 2020 FM is an index of the fineness of an aggregate the higher the FM, the coarser the aggregate. The FM can be looked upon as a weighted average size of a sieve on which the material is retained, the sieves being counted from the finest. Different aggregate grading may have the same FM.

Step 2 Get Price AM vs FM Whats The Difference Between AM And FM?
Aug 11, 2021 Although the FM is most commonly computed for fine aggregates, the FM of coarse aggregate is needed for some proportioning methods. It is calculated in the same manner, while taking care to exclude sieves that are not specified in the definition (for example, 25.0 and 12.5 mm l and 1/2 in. sieves) and to include all of the specified finer sieves.

Coarse Aggregate Dolomite Crushed Stone (Average 1155Kg) The material properties are given in Table 1. When we choose very fine sand (i.e. FM 2.0), and very coarse sand (i.e. of FM 3.0), and if the proportion of sand is fixed in the mix then due to poor all-inaggregate grading, the mix may become very harsh or not give correct results.
Fineness modulus of different type of sand is as per given below.The fineness modulus (FM) for both fine and coarse aggregates is obtained by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100.The FM is an index of the fineness of the aggregate. The higher the FM, the coarser the aggregate.Fine and Coarse Aggregates Front Desk

To find fineness modulus of coarse aggregate we need sieve sizes of 75mm, 37.5mm, 19mm, 9.5mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve size to higher order sieve. So, in the calculation of
maximum size coarse aggregate and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per unit volume of concrete mix can be estimated. FINENESS MODULUS (FM) - The fineness modulus (FM) is a factor obtained by adding the percentages of material in a sample of aggregate that is retained on each of the
The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1).

4- Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates). 5- A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample. Sieve Analysis
Mar 02, 2018 Results are expressed as mass per volume. For example, a given crushed limestone could weigh 93 lbs./ft.3. By knowing the DRUW of a coarse aggregate, the maximum nominal aggregate size and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per cubic yard of concrete mix can be estimated.
For a good fine aggregate, the FM should be between 2.3and 3.1 (ASTM Range for fine aggregates). 5 A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample.
