Sep 01 2014 · In Todays world Fineness modulus is not used for getting idea about fineness on material it is also omitted from IS Code More ever this value wont make any sense as it can get manipulated easily and it can show sand as fine but in reality its a coarse and vice a versa

river sand is that of obtaining required grading with a fineness modulus FM of 2 4 to 3 1 Generally FM of 2 2 to 2 6 2 6 to 2 9 and 2 9 to 3 2 indicates that the sand is fine medium and coarse confirming to grading zones ranging from IV to I IS383 It has been verified and found at various locations

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

Fineness Modulus is used to know the size of aggregate grains Particles for various measurements used in Civil Engineering To characterize the overall coarseness or fineness of an aggregate a

Sand samples of three different fineness moduli 1 3 1 5 and 1 7 were used and six different percentages 0 3 5 8 10 15 by weight of fines content were simulated for each fineness modulus

Fineness modulus Summation of cumulative of weight retained up to 150 microns 100 Fineness modulus 240 100 Fineness modulus 2 4 So in our case it is Fine Sand Value of fineness Modulus of Sand

verified that higher fineness modulus of sand would yield better performance for the concrete but so far there have been scarce amount of paper reported on the mix design method adopting high fineness modulus of sand Approach This study discussed the revolution of design mix proportion towards

FINENESS MODULUS The fineness modulus is an indicator of the fineness of an aggregate and is most used for evaluating fine aggregates The higher the number the coarser the aggregate The fineness modulus is computed by adding the cumulative

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

Follow the steps shown below to blend aggregate using fineness modulus value Step by Step Guide for Blending Aggregates Using Fineness Modulus Value Step 1 Calculate Fineness Modulus of Fine Aggregate Sieve the fine aggregate using sieves ranging from 80 mm to 150 micron Calculate the cumulative percentage of retained aggregate on each sieve
