Fineness Modulus of Sand for Concrete Fineness of fine aggregate is related to term fineness modulus ; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete .

Get PriceFineness Modulus. It is the cumulative percentage retained on standard sieve 150μm or sieves No 100 and above divided by 100. It is a single factor or an empirical number which we get from the results of sieve analysis. The value of FM will not change if we add non standard sieves in standard set of sieves.

Get PriceBased on the practical experience, the fineness modulus of fine aggregate should be between 2 to 3.5 and of coarse aggregate between 3.5 to 8. Usually, the Fineness modulus is calculated for fine aggregate rather than for coarse aggregate. Sieve Analysis of Soil Test. Designation: ASTM D421, D422. AASHTO T87, T88. Apparatus: 1. Set of sieves. 2.

Get PriceFineness Modulus Test for Aggregates A2) Fineness modulus method: In the fineness modulus method, the fineness modulus of sand and aggregates is determined by the standard tests. The term fineness modulus is used to indicate an index number which is .

Get PriceMar 07, 2016 · Fineness modulus gives the idea about how course or fine the sand is. Lower FM indicates fine sand and higher FM indicates courser sand.Fine sand requires more cement paste due to high surface area and tendency to develop crack.

Get PriceAug 10, 2017 · What is Fineness Modulus of Sand? 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.

Get PriceThe Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample.

Get PriceFineness 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.

Get PriceFineness 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 subdivided by 100 gives the value of fine aggregate.

Get PriceFineness modulus is the sum of the total percentages of the aggregate retained on each sieve divided by 100. Natural sand or crushed stone is used to achieve a fine rating, with most particles passing through a .

Get PriceFine aggregate is classified as coarse sand, medium sand and fine sand based on the fineness modulus (IS 2386 - PART III 1963) as shown in Table 3.6.

Get PriceJun 02, 2012 · The sand is good if its fineness modulus is in the range of 2.3 to 3.1. The sand with fineness modulus less than this will be called fine sand which is not good for use. The sand with fineness modulus greater than this will be called coarse sand, which is again not good for use.

Get PriceFineness Modulus of Sand for Concrete Fineness of fine aggregate is related to term fineness modulus ; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete .

Get PriceTo find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. 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.
