### What is Fineness Modulus of Sand (Fine Aggregate) and ...

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.

### What Is Fineness Modulus of Sand? - Civil Lead

Aug 14, 2019 · Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate. It is found out by sieve analysis test of standard size in the laboratory. The thumb rule is lower the fineness modulus, particles are smaller and higher the fineness modulus, particles are larger.

### Fineness Modulus - an overview | ScienceDirect Topics

The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6. And if Mx is within 3.7 ~ 3.1, it is coarse sand; if Mx is within 3.0 ~ 2.3, it is medium sand; if Mx is within 2.2 ~ 1.6,...

### FINENESS MODULUS OF AGGREGATE – WHAT, WHY & HOW ...

### What is Fine Aggregate? FA Types used in Construction ...

The fineness modulus sand should be between 2 and 3. A smaller value of fineness modulus indicates the presence of finer particles and vice versa. If good sand is not available in the nearby of the site, the substitutes may be used as fine aggregate.

### THE ROLE OF FINENESS MODULUS - Southport Concrete Co

Jul 20, 2018 · Fineness modulus offers a way to quantify the average size of the aggregate particles in the concrete mix. The size of the particles, in turn, will greatly affect how easily the concrete pours and spreads, as well as its strength and durability once cured.

### CHAPTER 2 SIEVE ANALYSIS AND FINENESS MODULUS …

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.
