Fineness Modulus an overview ScienceDirect Topics

Fineness modulus of various soil samples in the study area varied from 0.67 to 7.01 with mean of 3.35 and standard deviation of 2.38. This implies that the weighted average size of a sieve on which the material is retained is between the third sieve, size 0.212 mm (sieve No.70 ASTM) and the fourth sieve, size 300 mm (sieve No.50 ASTM) when

Fineness Modulus of Aggregates: The Inside Scoop

The fineness modulus (FM) of aggregates can be an intimidating term, but it’s just an empirical value that describes the average size of particles in a sample of aggregate. This factor provides a basis to select estimated proportions for concrete mix design, but its real influence is not always understood.

What is Fineness Modulus of Sand (Fine Aggregate)

What Is Fineness Modulus of Sand? 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.

Fineness Modulus Method of Concrete Mix Design

Fineness Modulus Method of Concrete Mix Design The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM). Fineness modulus is determined separately by sieving coarse and fine aggregates through the following set of sieve. IS sieves for coarse aggregates are 80 mm, 40 mm, 20 mm, []

The Importance of Fineness Modulus| Concrete

1994-1-1 · The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength." Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.
