The fineness modulus is define in ACI terminology as “A factor obtained by adding the total percentages of material in the sample that are coarser than each of the following sieves (cumulative percentages retained), and dividing the sum by 100: 0.15 mm (No. 100),0.30 mm (No. 50), 0.60 mm (No. 30), 1.18 mm (No. 16),2.36 mm (No. 8), 4.75 mm (No. 4), 9.5 mm (3/8in.), 19.0 mm

MoreFineness 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.

MoreFineness modulus = (Summation of cumulative % of weight retained up to 150 microns) / 100. Fineness modulus = 240/100. Fineness modulus = 2.4. So, in our case, it is Fine Sand.

More01/09/2014· Following procedure is adopted to calculate fineness modulus of aggregate. Procedure. Sieve the aggregate using the appropriate sieves (80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron & 150 micron) Record the weight of aggregate retained on each sieve. Calculate the cumulative weight of aggregate retained on each sieve. Calculate the cumulative

MoreFineness 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 cumulative percentage retained on 300µm, 150µm should be entered as 100.

MoreSIEVE 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. Therefore, when sampling, it is important to obtain a representative sample
