31-08-2020· Fineness Modulus. It is the cumulative percentage retained on standard sieve 150μm or sieves No 100 and above divided by 100. It is a single factor or an empirical number which we get from the results of sieve analysis. The information obtained from fineness modulus is …
modulus hence fineness modulus of coarse aggregate is higher than fine aggregate. To find fineness modulus of coarse aggregate we need sieve sizes of 75mm, 37.5mm, 19mm, 9.5mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve ...

To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus …
5 · 31-07-2016· Fineness modulus of coarse aggregates represents the average size of the particles in the ...
22-06-2021· More fineness modulus value indicates that the aggregate is a coarse sand small value of fineness modulus indicated that the aggregate is finer. Fineness modulus is a factor obtained by adding the cumulative percentages of aggregate retained on each of the sieves ranging from 80 mm to 150 mm micron and dividing this by 100.
11-06-2021· Add the cumulative weight of aggregate and calculate the fineness modulus using formula: Fineness modulus for fine aggregates = ∑ 100; Fineness modulus for coarse aggregates = ∑ + 5 100; Where, C denotes the cumulative percentage of mass retained in a sieve. Determine the grade of aggregates from the Table 1 and the Table 2.
Coarse aggregate 2703 323 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 475mm to 150 microns and dividing the sum by an arbitrary number 100 The larger the value, the coarser is …
11-06-2021· Fine aggregate is sand used in mortars. Coarse aggregate is broken stone used in concrete. The size of the fine aggregate is limited to maximum 4.75 mm (4800 microns) beyond which it is known as coarse aggregate. Fineness modulus is only a numerical index of fineness, giving some idea about, the mean size of the particles in the entire body of ...
Fineness Modulus of Aggregates The Inside Scoop. An example provided in the ACI 211 standard states that For a fine aggregate having a fineness modulus of 28 and a 375mm nominal maximum size of coarse aggregate the table indicates that 071m3 of coarse aggregate on a dry-rodded basis may be used in each cubic meter of concrete The required dry mass is therefore 071 x 1600 = 1 136kg...
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.
Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of …
Kalra [13] studied the effect of coarse aggregate size on strength of high performance concrete (HPC). Three sizes of coarse aggregates 10mm, 12.5mm and 16mm with two types of fine aggregate with fineness modulus 2.65 and 2.88 were used in the study. It was concluded that concrete made with 10mm size coarse aggregate showed
Therefore fineness modulus of coarse aggregates = sum cumulative retained / 100 = 717/100 = 717 Fineness modulus of 717 means the average size of particle of given coarse aggregate sample is in between 7 th and 8...
