Nature sand river sand particles are round and smooth. The fineness modulus of natural medium sand is mostly 2. 6 3.0 with better gradation which is very beneficial to the workability of concrete. The sand has sharp grains multiple edges and corners rough surface and the fineness modulus is
b As per the grading given in Table 1 the fineness modulus of sand could vary from I.2 to 2.2. However it is preferable to have minimum fineness modulus of l-4 in case of crushed stone sands and crushed gravel sands and a F. M of 1 5 in case of naturally occurring sands. Hence
Manufactured sand is widely used today but the research activities about its characteristics are still not deepgoing. . with the river sand the fineness modulus of manufactured . sand may .
The fine aggregate shall consist of natural sand manufactured sand or a combination thereof. 1. Grading. The fine aggregate shall not pass 45 from a single sieve and retained on the next consecutive sieve as shown in table-1. The fineness modulus of the
At present the general requirement for fineness modulus of manufactured sand is 2.6-3.0. The sieve size is generally recommended to be 3.0 mm or 3.5 mm. If the content of stone powder is high 2.8mm screen can be considered if it reaches about 2.3 long screen such
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.
Effect of Fineness Modulus of Manufactured Sand on across south India that it has become increasingly difficult to get river sand of consistent quality in terms of grading requirements and limited silt clay content In case of manufactured sand with welldesigned screening system the required grading and fineness modulus 24 to 31 can be .
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
the specific gravity is 2.65. The Fineness modulus of river sand is 5.24. Manufactured Sand M-Sand was used as partial replacement of fine aggregate. The bulk density of Manufactured sand was 1.75 kgm3 specific gravity and fineness modulus was found to be 2.73 and 4.66 respectively. The percentage of particles passing
Fine aggregates were manufactured sand prewashing and desert sand and the fineness modulus of manufactured sand was 3.0. The macroscopic appearance of all desert sands is shown in Figure 1.Four desert grains of sand from the Chinese areas of Kubuzi Maowusu Tengger and Ulanbuh were used with fineness modulus values of 0.27 0.30 1.03 and 0.57 respectively.
Manufactured-sand possesses coarser grading which is above the upper limit of ASTM C33-03. According to ASTM C33-03 the fine aggregate has not more than 45 passing any sieve and retained on the next consecutive sieve and its fineness modulus not less than 2.2 and not more than 3.2.
2 Higher fineness modulus particles grading shape texture and control of microfines have contributed to better workability of Manufactured sand. The good physical properties of Manufactured sand has enabled in reduction of free water as well. 3 The river sand particles have better shapeand
Fineness modulus of sand is an index arrived based on the particle size analysis and then dividing the sum of the cumulative percentage of particles retained on the sieves by 100. it is important to note that higher the fineness modulus higher is the coarser portion of the sand. The fineness modulus plays very important role in mix proportion .
fineness modulus and grading of the different fine aggregates. In general MS is coarser than LS and RS. LS is uniformly graded with a 2.36-mm maximum size. As indicated in Table 2 the fineness modulus of RS MS and LS is 2.77 3.45 and 2.96 respectively. A locally-available superplasticizer that complied with BS EN 480-132009 was utilized to
Apr 01 2017 The fineness modulus of manufactured sand was 2.23.55. As these studies were done based on different codes different maximum particle sizes of 0.075 mm and 0.160 mm were defined for stone powder in manufactured sand.
B. Properties of Manufactured sand The properties of M-sand is found out and the results are given. The bulk density of manufactured sand is 1862 Kgm3and the specific gravity is 2.50.The fineness modulus of M-sand is 2.68.The sieve analysis revealed that the fine aggregate falls in Zone
Apr 21 2021 Mixed sand fineness modulus C60 The fineness modulus of the mixed sand shall not be less than 2.3 and the fineness modulus of the ultra-fine sand shall not be less than 1.1. C45-C55 The mixed sand fineness modulus is not less than 1.8 and the ultra-fine sand fineness modulus is not less than 0.9. C60 or more
Fineness Modulus FM 3.0 Minus 200 sieve 75 m material 7 They are from finer fractions of crushed stones a.k.a manufactured sand. East Region Concrete Division. Why non traditional fine aggregates Looming natural sand shortage due to Urban sprawl and NIMBY Permitting issue
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.
Jul 20 2018 Fineness modulus also provides important information about the density of the resulting concrete as well as its compressive strength. Both of these factors must be taken into consideration when designing the concrete. For more information about the role played by fineness modulus contact the concrete experts at Southport Concrete Corp.
Jul 30 2016What Is Fineness Modulus of Sand 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 of fineness modulus.
manufactured sand the process of attrition through VSI and washing makes the crushed stone sand particles good enough to be compared shape and surface texture of natural sand. With well-designed screening system the required grading Zone II and fineness modulus 2.4 to 3.1 can also be achieved consistently in the case of manufactured sand.
