Artifical sand is a kind of sand material produced by sandmaking equipment, such as impact crusher. Compared with natural river sand, artifical sand has the characteristics of sharp edges, many needles and flakes, and rough. River sand is directly excavated from the river, so it will be mixed with small pebbles and fine sand.

Calculation of fineness modulus of Sand. Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = Fineness modulus of fine aggregate is It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in between to as shown in below figure.

The sieves used for determining the fineness modulus are: No. 100 (150 µm), No. 50 (300 µm), No. 30 (600 µm), No. 16 ( mm), No. 8 ( mm), No. 4 ( mm), 10 mm,20mm, 40mm etc. As per our experience Fine Aggregate with of to are best suited concrete application and Fine Aggregate with of to are best suited plaster applications

· 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 .

fineness modulus of sand . Stone Crusher. SEM has been serving the stone crushing grinding industry for over 20 years, it is one of the most famous stone and mineral processing company in the ...

A fineness modulus for fine aggregates should be Two aggregates with the same fineness modulus can have different grading curves. A low fineness modulus requires more cement paste to maintain workability. Variations from mix design requirements for fineness modulus should not exceed (ASTM standards).

A comparison of three maximum size gradings of sandgravel and sandcrushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich, if the cement is included in the modulus figures.

Limits of Fineness Modulus. Fineness modulus of coarse aggregate varies from to And for all in aggregates or combined aggregates fineness modulus varies from to Range of fineness modulus for aggregate of different maximum sized aggregates is given below.

Fineness Modulus Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from to 150 microns and dividing the sum by an arbitrary number 100. The larger the value, the coarser is the material.

The resulting figure gives fineness modulus of the respective aggregate. This is illustrated in the following example. A weight of 10 kg of Coarse aggregate and 5 kg of fine aggregate has been taken to determine fineness modulus in each case separately.
