CHAPTER 3 - PHYSICAL PROPERTIES OF LIGHTWEIGHT AGGREGATE

Fineness modulus (by weight) 3.03 fineness modulus (by volume) = 3.23 A fineness modulus of 3.23 by volume as shown in Table 3.1 indicates a considerably coarse grading than that normally associated with the fineness modulus of 3.03 by weight. Therefore lightweight aggregates require a larger percentage of material

CHAPTER 2 SIEVE ANALYSIS AND FINENESS MODULUS Sampling

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. The results of testing will re" ect the condition and characteristics of the aggregate from which the sample is obtained.

What Is Fineness Modulus of Sand? - Civil Lead

Fineness Modulus of Sand. 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.

Fine Sand: the fineness modulus is 2.2-1.6 and the particles with particle size greater than 0.075mm exceed 85% of the total weight and the average particle size is 0.25mm-0.125mm. 4. Ultra Fine Sand: the fineness modulus is 1.5-0.7 and the average particle size is less than 0.25mm.

What is Fineness Modulus of Sand (Fine Aggregate) and Calculation

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 and how to calculate it

Fineness modulus gives the idea about how course or fine the sand is. Lower FM indicates fine sand and higher FM indicates courser sand.Fine sand requires more cement paste due to high surface area and tendency to develop crack.

Fineness Modulus Of Sand - Apparatus Procedure & Result

The Fineness Modulus of Sand is an index number that indicates the mean size of the sand particles. It is calculated by performing the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from 2.2 to 3.2.

Fineness Modulus - an overview | ScienceDirect Topics

The coarseness of sand is expressed by fineness modulus ( Mx ) defined as follows: (5.1) M x = A 2 + A 3 + A 4 + A 5 + A 6 − 5 A 1 100 − A 1. 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.

What Is Fineness Modulus of Sand (Fine Aggregate)? 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 subdivided by 100 gives the value of fine aggregate.

Fineness Modulus of Aggregates: The Inside Scoop - Gilson Co.

An example provided in the ACI 211 standard states that "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate the table indicates that 0.71m3 of coarse aggregate on a dry-rodded basis may be used in each cubic meter of concrete. The required dry mass is therefore 0.71 x 1600 = 1136kg."

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. Sieves sizes are: 150-μm (No. 100) 300-μm (No. 50) 600-μm (No. 30) 1.18-mm (No. 16) 2.36-mm (No. 8) 4.75-mm (No. 4) 9.5-mm (3/8-in.) 19.0-mm (3/4-in.) 37.5-mm (11/2-in.) and larger increasing in the ratio of 2 to 1.

What is the fineness modulus range for good quality sand? The fineness modulus is define as a factor obtained by adding the total percentages of material in the sample. Fineness modulus gives the idea about how course or fine the sand is. The fineness modulus range for fine sand is 2.2-2.6 for medium san is 2.6-2.9 while coarse sand is 2.9-3.2 2.
