· Fineness Modulus – an index describing the fineness or coarseness of an aggregate. It is calculated by adding up the cumulative percent of retained aggregate on each sieve (from a samples sieve analysis chart – ex. figure 2, above) and dividing it by 100.
· Fineness modulus is a numerical index of fineness that gives some idea about the mean size of the particles in the References: Fine aggregate, often called sand ( BS 882: 1992) are those granular materials having size not larger than 5mm. coarse aggregate are
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. The results of testing will re" ect the

ability of equipment to withstand specified severltles of vibration, shock, temperature, humidity, etc. The re-quirements may be set by the user or the supplier with reference to some national or military standard. These standards describe the test procedures, but
· The fineness modulus of Fine Aggregate is 2.44. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates).Our result lie in this range as the graph shows that our sample is lies b/w maximum and minimum cumulative
The Fineness Modulus is an index number that indicates the mean size of the sand particle. It is calculated by the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from 2.2 to 3.2. The formula for its calculation is, Fineness modulus of Sand = (Cumulative % retained) / 100.
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 = 1,136kg."
The fineness modulus of coarse aggregates is the index number of the total particle size of the coarse aggregate doing sieve analysis with normal sieves, it is measured.The accumulated percentage retained on each sieve is applied and the coarse aggregate valuation is given by subdividing it by 100. ...
Fineness modulus method Minimum voids Method Arbitrary Method By this method such mixes as 1:1.5:3 ( 1 part cement, 1.5 part sand and 3 part coarse aggregate). 1:2:4, 1:3:6 are arbitrarily chosen by volume. The quantity of water required for mixing is
1. Listen carefully to the lecture given by teacher about importance of the subject, background theory, learning structure, skills to be developed, information about equipment, method of continuous assessment, tentative plan of work in laboratory and total amount of
Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 9.5mm to 19mm. Limits …
· v) Fineness modulus is obtained by adding cumulative percentage of aggregates retained on each sieve and dividing the sum by 100. Reporting of Results The results should be calculated and reported as: i) the cumulative percentage by weight of the total sample ii) the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve, to the nearest 0.1 ...

and Machine Iron Slag (MIS) as partial replacement of coarse aggregate in concrete. Coarse aggregates were partially ... fineness modulus (FM) was conducted in accordance with BS 812-103.1 [20 ...
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 ...
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 counted from the finest sieve.
· The Importance of Fineness Modulus. In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. 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 ...
