7/30/2016 · Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. 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 fine aggregate .
9/1/2014 · Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividi ng this sum by 100. Fineness Modulus of Sand.
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.
The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm, and 0.15mm sieve sizes. The fineness modulus of the finer aggregate is greater than the coarse aggregate fineness module. Also, Read: What Is …
What is fineness modulus of aggregate? The fineness modulus of aggregate is simply a measurement of the average size of the aggregate. It can be calculated with the help of different sizes of the sieve. Now, let us see some numerical Examples to calculate the fineness modulus of aggregate.
What is Fineness Modulus of Coarse Aggregates and Its Calculation, What is Fineness Modulus of Coarse Aggregates and Its Calculation, What is Fineness Modulus of Coarse Aggregates and Its Calculation, What is Fineness Modulus of Coarse Aggregates and Its Calculation, 3/14/2018 · 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 is the number at which the average …
8/31/2020 · Fineness Modulus . It is the cumulative percentage retained on standard sieve 150?m 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 helpful in the following ways, 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 condition and characteristics of the aggregate from which the sample is obtained.
