Significance and Use A method of selecting mixture proportions Fineness = 9(100) 156 = 900 156 for concrete based on the fineness modulus of the Modulus 100 100 combined fine and coarse aggregate was proposed Fineness by Abrams in 1918
[Live Chat]For aggregates used in PCC another common gradation description for fine aggregate is the fineness modulus It is described in ASTM C 125 and is a single number used to describe a gradation curve It is defined as The larger the fineness modulus the more coarse the aggregate
[Live Chat]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 siev The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness

[Live Chat]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
[Live Chat]As fineness modulus of sand changes from 20 to 25 there is an increase in compressive strength from 4307 to 4900 MPa ie strength increases by 14% On the other hand by increasing Fineness Modulus from 25 to 3 Compressive strength increases from 4900 to

[Live Chat]Jan 13 2018· Many a time fine aggregates are designated as coarse sand medium sand and fine sand These classifications do not give any precise meaning What the supplier terms as fine sand may be really medium or even coarse sand To avoid this ambiguity fineness modulus could be used as a yard stick to indicate the fineness of sand
[Live Chat]FINENESS MODULUS OF FINE AGGREGATE TxDOT Designation Tex 402 A Effective Date August 1999 1 SCOPE 11 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete 12 The values given in parentheses (if provided) are not standard and may not be exact
[Live Chat]Fineness modulus estimates the proportions of aggregate in construction materials Aggregate is inert granular material such as sand gravel or crushed stone used to form concrete The fineness modulus number affects the workability and finish of concrete Before calculating fineness modulus lab technicians pour aggregate onto siev Fineness
[Live Chat]A comparison of three maximum size gradings of sand gravel and sand crushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich if the cement is included in the modulus figur Chat online
[Live Chat]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 So in the calculation of coarse aggregate we need

[Live Chat]want a return to coarser higher fineness modulus sands to get away from water demand related shrinkage issu Most reports of the use of aggregate optimization point out the benefits of using a more well graded material including less paste and hence less concrete shrinkage greater strengths better pumpability and enhanced finishability
[Live Chat]This specification covers fine aggregate for use in bituminous paving mixtur The aggregate shall be sampled to meet the requirements prescribed Grading fineness modulus and plasticity index shall be tested to meet the requirements prescribed This abstract is a brief summary of the referenced standard
[Live Chat]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 Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is
