fineness modulus of natural sand

As fine aggregate comprises up to 30 of the total volume of concrete consequently gradation and fineness modulus of sand are among principal factors affecting the performance of fresh and The average value of fineness modulus is found The zoning of aggregate as per IS PART III is found The test results are given in table 5 for natural sand and table 6 for manufactured sand Respective graphs for natural sand and manufactured sand is shown in fig2 and Both natural sand and manufactured sand falls under zone 2

با ما تماس بگیریدLimits of Fineness Modulus Fineness modulus of coarse aggregate varies from 55 to 80 And for all in aggregates or combined aggregates fineness modulus varies from 35 to 65 Range of fineness modulus for aggregate of different maximum sized aggregates is given belowAs fineness modulus of sand changes from 20 to 25 there is an increase in compressive strength from to MPa ie strength increases by 14 On the other hand by increasing Fineness Modulus from 25 to 3 Compressive strength increases from to

با ما تماس بگیرید“Effect of Specific Gravity on Aggregate Varies the Weight of Concrete Cube “ Fineness Modulus of coarse aggregate varied for different location The variation in Fineness modulus natural or synthetic which weight more than Kg/m3Althoughaggregates are most commonly known to be inert filler in concrete the different Finess Modulus is just a value number indicating the fineness or coarseness of the aggregate So a river sand natural sand will be in the range of25 or so to 27 and P gravel P stone Birds

با ما تماس بگیریدFor instance a fineness modulus of 400 can be interpreted to mean the the fourth sieve No 16 in the US series is the average size It is important to note that the fineness modulus is just one number which only characterizes the average size of the aggregate and different gradings may have the same fineness modulusWhat is the finess modulus of sand Answer / dr savitha natak 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
