Values of Fineness Modulus of Sand. Fineness modulus of fine aggregate varies from 2.0 to 3.5mm. Fine aggregate having fineness modulus more than 3.2 should not considered as fine aggregate. Various values of fineness modulus for different sands are detailed below.
How to calculate Fineness Modulus Procure to determine Fineness Modulus. Sieve the aggregate using the appropriate sieves 80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron and 150 micron Note down the weight of aggregate retained on each sieve. Calculate the cumulative weight of aggregate retained on each sieve. Fi
The value for tine aggregates commonly ranges from 2.00 to 4.00 and for coarse aggregate from 6.50 to 8.00 when all the material is finer than the 11/2in. 4.2 As noted in the standard definition of fineness modulus para 1.1 and the example shown in para 4.1, the fineness modulus is based on the percentages of aggregates retained on a specificed
2.1 The values used in computing fineness modulus shall be obtained by tests conducted in accordance with CRDC 103. 3. Range of Values 3.1 The same value of fineness modulus may be obtained from several different particlesize distributions. In general a small value indi ed a fine material while a large value indi es a coarse material.
calculation of fineness modulus enter values of z and press calculate actual program is available in super civil cd. is sieve size passing of sand z pure sand: x: 100 x: 4.75 mm: 2.36 mm: 1.18 mm: 600 microns: 300 microns: 150 microns
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.
The same value of fineness modulus may therefore be obtained from several different particle size distributions. In general, however, a smaller value indi es a finer aggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.75 to 8.00.

For this reason, ASTM C33/C33M states that, for continuing shipments from a given source, the fineness modulus of fine aggregate should not vary by more than 0.20 from the value that is typical of the source base fineness modulus . If the base fineness modulus is different from that used in selecting proportions of the concrete, suitable ...
Fineness modulus value can be used as a technical way to blend coarse aggregate with fine aggregate to produce desired grading. Follow the steps shown below to blend aggregate using fineness modulus value.
