Automatic control of fineness modulus is the key technology in this process. Typical features are listed below in detail. 1. German sand producing host machines are equipped and of low energy consumption, low cost, good particle shape, and stable grading. The impact rotors in two cavities largely increase the crushing effect and reduce the ...

Fineness Modulus of Aggregates The Inside Scoop - Fineness Modulus of Sand. To calculate the fineness modulus of sand, the sum of the cumulative percentages retained on the following sieves are divided by 100 150m No. 100, 300m No. 50, 600-m No. 30, 1.18mm No. 16, 2.36mm No. 8, and 4.75mm No. 4 for fine aggregates.

The object of this experiment is to determine the fineness modulus and hence to plot the particle size distribution curve for the sample of fine aggregate supplied. Theory The fineness modulus of a sample of aggregate is an index number which is roughly proportional to the average size of particle in the aggregate, that is, coarser the ...

Mar 07, 2016· Fineness Modulus Range: Fine Sand: 2.2 – 2.6: Medium Sand: 2.6 – 2.9: Coarse Sand: 2.9 – 3.2: How to calculate Fineness Modulus Procure to determine Fineness Modulus. 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)

A higher fineness modulus represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface ...

The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading. It is defined as the summation of the cumulative percent retained ...

Jan 01, 1994· The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength." Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.

Fineness Modulus For Sand By Luke M. Snell and Bryan Castles 1 This paper was published in the Proceedings of the 10th Annual Mongolian Concrete Conference. Papers at this conference are published in either Mongolian or English.

As fineness modulus of sand changes from 2.0 to 2.5 there is an increase in compressive strength from 43.07 to 49.00 MPa. i.e. strength increases by 14%. On the other hand by increasing Fineness Modulus from 2.5 to 3, Compressive strength increases from 49.00 to …

Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate. It is found out by sieve analysis test of standard size in the laboratory.

FINENESS MODULUS OF FINE AGGREGATE TXDOT DESIGNATION: TEX-402-A CONSTRUCTION DIVISION 1 – 2 LAST REVIEWED: SEPTEMBER 2014 Test Procedure for FINENESS MODULUS OF FINE AGGREGATE TxDOT Designation: Tex-402-A Effective Date: August 1999 1. SCOPE 1.1 This method determines the fineness modulus of concrete fine aggregate used in

Fineness Modulus of Aggregates The Inside Scoop - Fineness Modulus of Sand. To calculate the fineness modulus of sand, the sum of the cumulative percentages retained on the following sieves are divided by 100 150m No. 100, 300m No. 50, 600-m No. 30, 1.18mm No. 16, 2.36mm No. 8, and 4.75mm No. 4 for fine aggregates.

1. The aggregate should be hard, clean and well graded; the fineness modulus of artificial sand should be in the range of 2.4-2.8, and that of natural sand should be in the range of 2.2-3.0. 2. The moisture content of aggregate should be stable. The moisture content of artificial sand should not exceed 6%.

Jul 30, 2016· 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.

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 …

Title: Concrete Mix Design- A modification of the Fineness Modulus Method Author(s): Myron A. Swayze and Ernst Gruenwald Publication: Journal Proceedings Volume: 43 Issue: 3 Appears on pages(s): 829-843 Keywords: none Date: 3/1/1947 Abstract: A comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of …

Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve size to higher order sieve. So, in the calculation of coarse aggregate we need ...

Fineness modulus of sand range. Calculation of fineness modulus of Sand Therefore fineness modulus of aggregate cumulative retained 100 275 100 275 Fineness modulus of fine aggregate is 275 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 03mm to 06mm as

The same value of fineness modulus may therefore be obtained from several different particle size distributions. In general, however, a smaller value indicates a finer aggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.75 to 8.00.
