· Normally, Dense sand will have more bearing capacity than loose sand as the unit weight of dense sand is more than loose sand. If the bearing capacity of soil is sufficient to take a load of the structure at shallow depth, then a shallow foundation is provided and the option for shallow are combined footing, Isolated footing, or strip footing.
· 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.
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
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.
· Fineness modulus is typically used for sand or cement mixes, which will typically fall within an FM of 2 - 4, with most coming in between 2.2 - 2.8. As a general rule, the lower the fineness modulus, the finer the particles will be, and the higher the fineness modulus, the coarser they will be.

· Limits of Fineness Modulus Fineness modulus of coarse aggregate varies from 5.5 to 8.0. And for all in aggregates or combined aggregates fineness modulus varies from 3.5 to 6.5. Range of fineness modulus for aggregate of different maximum sized aggregates is given below.
· Extra fine sand: fineness modulus is 1.5-0.7, and the average particle diameter is less than 0.25 mm. 2. According to the density of aggregate The density of aggregate refers to the ratio of the dry mass per unit volume to the volume of drainage in the natural
· Medium sand: The fineness modulus is 3.0-2.3, and the average particle size is 0.5-0.35mm. Fine sand: The fineness modulus is 2.2-1.6, and the average particle size is 0.35-0.25mm. Extra-fine sand: The fineness modulus is 1.5-0.7, and the average particle size is less than 0.25mm. 3. Other specifications of sand and gravel.
Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the ...

· Step-1 (Calculate Fineness Modulus of Fine Aggregate) Sieve the fine aggregate using sieves ranging from 80 mm to 150 micron. Calculate the cumulative percentage of retained aggregate on each sieve. Add all the values of Percentage of retained on each sieve. Divide the sum, calculated as above, by 100. This gives the fineness modulus value of ...

The fineness modulus is exactly what it sounds like: a measure of how fine or coarse an aggregate is. This factor is obtained by adding the total percentages by weight of an aggregate sample retained on each of a specified series of sieves, and dividing the sum by 100.
and fineness modulus is given by Table 4. The value from the table multiplied by the dry-rodded unit weight (the oven-dry (OD) weight of coarse aggregate required per cubic foot of concrete). To convert from OD to saturated surface dry (SSD) weights, multiply by
Fineness Modulus of an aggregate sample represents the average size of the aggregates of the sample. Higher the size of aggregates in the sample, higher is the Q18. Consider the following statement regarding the vane shear test. A The test is used to determine ...

Fineness Modulus (FM) The results of aggregate sieve analysis is expressed by a number called Fineness Modulus. Obtained by adding the sum of the cumulative percentages by mass of a sample aggregate retained on each of a specified series of sieves and
· It approximates the number of meshes per inch of that sieve that would just pass the sample if its grains of uniform size. It is approximately proportional to the surface area per unit of weight of sand, exclusive of clay. Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand.
