The fineness modulus is also considered as the indication of quality of aggregate. According to IS recommendations the aggregate should posses the to the range of to Greater than should be rejected. The Classification of sand based on Fineness modulus is as follows, Fine Sand .
Soil SubGrade Modulus SubgradeSubbase Strength Soil bearing capacity, soil compressibility, and soil modulus of subgrade reaction are various measures of strengthdeformation properties of soil. It is important to consider how these parameters apply to the design of floor slabs.
number called Fineness Modulus. Obtained by adding the sum of the cumulative percentages by mass of a sample aggregate retained on each of a specified series of sieves and dividing the sum by 100. The following limits may be taken as guidance: Fine sand : Fineness Modulus : Medium sand .
⇒ If the various concrete ingredients cement, sand and aggregates are in the ratio of 1:3:6, the grade of concrete, is. M 100 M 150 M 200 M 250 ⇒ The void ratio of. single size coarse aggregate is roughly graded coarse aggregate is roughly fine aggregate is roughly all the above.

As we know that Larger value of FM is preferred for fine aggregates For a good fine aggregate, the FM should be between and So, we can conclude that the Laurence pure sand is a good fine aggregate as the fineness modulus of Laurence pure sand is in between the given range of a good fine aggregate.
Soil Modulus Parameter k for Sands Relative Density Loose Medium Dense Submerged Sand Submerged Sand 20 lb/in3 5,430 KPa/m 60 lb/in3 16,300 KPa/m 125 lb/in3 33,900 KPa/m Sand Above WT Sand Above WT 25 lb/in3 6,790 KPa/m 90 lb/in3 24,430 KPa/m 225 lb/in3 61,000 KPa/m
side (fine or course) the gradations were running in relation to the limits, various combinations of sand and course aggregates A, B, or D were all over the Coarseness Factor chart, with behavior ranging from rocky to good to sandy. 17. Key Words: 18. Distribution Statement: Aggregate, gradation, concrete, optimization, sand,
But in case of fully saturated sand the water films are broken and the volume becomes equal to that of dry sand. Fineness Modulus. Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100.
For any type of mix proportioning sieve analysis results and fineness modulus is required. here is the excel sheet which includes calculations of fineness modulus. Hope it will consume less time in case of repetitive calculations. Excel Sheet For Sieve Analysis Of Aggregate And To Calculate Fineness Modulus
In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. 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 ...
Fineness Modulus Nature of sand 1 – Fine sand 2 – Medium sand 3 – Coarse sand Sand having a fineness modulus more than will be unsuitable for making satisfactory concrete. The fineness modulus values obtained for sand, quarry dust and coarse aggregate are given in Tables to
Effect of Fineness of Sand on the Cost and Properties of Concrete. Fineness Modulus is a term used as an index to the fineness or coarseness of ...
The modulus of elasticity or Young's modulus of a soil is an elastic soil parameter most commonly used in the estimation of settlement from static loads. Young's soil modulus, E s, may be estimated from empirical correlations, laboratory test results on undisturbed specimens and results of field tests.
