SCOPE 1.1 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete. 1.2 The values given in parentheses if provided are not standard and may not be exact
Read MoreAccording to the fineness modulus MX, the specifications of machine-made sand can be divided into 4 types coarse, medium, fine and extra fine 1. Coarse Sand the fineness modulus is 3.7-3.1, and the content of particles larger than 0.5mm exceeds 50 of the total weight, and the average particle size is
Read MoreIt is obtained when Fineness Modulus is about 2.7. The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5 for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the CostBenefit Ratio reduce by a very large factor. This
Read MoreWhat 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
Read MoreLimits 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.
Read MoreJul 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.
Read MoreFineness 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.
Read MoreQuestion is If fineness modulus of sand is 2.5, it is graded as., Options are A very fine sand, B fine sand, C medium sand, D coarse sand, E , Leave your comments or Download question paper.
Read MoreNov 30, 2020 Fineness Modulus of sand is a number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves 4.75 mm to 150 micron. The cumulative percentage retained on each sieve is added and divided by 100 to gives the value of fineness modulus.
Read MoreAug 31, 2020 Surface Area 1Fineness Modulus Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between 2.3 and 3.1 ASTM Range for fine aggregates. A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample.
Read MoreFineness 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.

Read MoreSB3 sand FM3.1 and SG5 sand FM2.2 were mixed to vary the fineness modulus from 2.2 to 3 and the compressive strengths of each corresponding mortar specimen determined after 28 days. The compressive strength of the mortar issued from the mixed sands is observed to be greater than that issued from the natural sand of the same fineness modulus.
Read MoreOct 14, 2016 Fine Aggregate and Fineness Modulus. Posted 2016-10-14 In civil engineering, aggregates with a particle size greater than 5 mm are coarse aggregates, also known as stone aggregates with a particle size of less than 5 mm are fine aggregates, also known as sand.Qualified fine aggregate should have a good gradation, including fineness modulus, firmness, mud content, sand
Read MoreIf fineness modulus of sand is 2.5, it is graded as very fine sand fine sand medium sand coarse sand
Read MoreSo, the Lawrencepur sand lies in the category of medium coarse sand The value of fineness modulus is between 2.5 and 3.1, hence it is good fine aggregate The graphs of the gradation curve are intersecting because the material is not well graded.
Read More3.2. Based on Fineness Modulus As per IS 1542 1992 clause 5.2, the fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sand and not less than 1.5 in case of naturally occurring sands. Lower FM indicates fine sand and higher FM indicates courser sand. 4. Result interpretation 4.1.
Read MoreTherefore, fineness modulus cannot be used as a description of the grading of aggregate. When the use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help. It reduces the ambiguity in the classification of fineness of sand.
Read MoreNatural sand was replaced by M-sand at levels of 20, 40, 60, 80, and 100. Flow test was conducted on all mortars and the effect of M-sand replacement on flow characteristics was studied.
Read MoreFineness Modulus of Fine Aggregate. Fine aggregates is the sand used in mortars. The size of the fine aggregate is limited to maximum 4.75mm beyond which it is known as coarse aggregates. Fineness modulus is only a numerical index of fineness that gives some idea about the mean size of the articles in the entire body of concrete.
Read MoreThe value for tine aggregates commonly ranges from 2.00 to 4.00 and for coarse aggregate from 6.50 to 8.00 when all the material is finer than the 1-12-in. 4.2 As noted in the standard definition of fineness modulus para 1.1 and the example shown in para 4.1, the fineness modulus is based on the percentages of aggregates retained on a ...
Read MoreJan 01, 1996 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.
