a mass of material to determine the aggregate 10% fines value. b) Test specimen in a dry condition (i) Sieve the entire dried test portion on the 14 mm and the 10 mm test sieve to remove the oversize and undersize fraction. Divide the resulting 14 mm to 10 mm size fractions to produce 3 test specimens each of sufficient mass such

Ten Per Cent Fines Value (TFV) Ten per cent fines value – dry – particle size 10 mm and greater : BS 812-111:1990 Ten per cent fines value – soaked – particle size 10 mm and greater : BS 812-111:1990

The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve.

For Fine aggregate, ... To calculate aggregate Crushing value by testing aggregate passing 12.5 mm sieve and retained on a 10 mm sieve. Scope: This procedure covers all relative activity for the project site. ... (For 20 mm down an aggregate size ) and through 2.36 mm (For 12.5/10 mm down an aggregate size).

Feb 08, 2012· If the percentage fines lies between 7.5% and 12.5%, the following calculation for Ten Percent Fines Value (TFV) is made: 14x TFV = Force to produce 10% fines = . . . (3) y + 4 where x = maximum force used (kN) y = percentage fines from the test (%) The result should be reported to the nearest whole number.8.

CIVIL ENGINEERING MATERIAL TESTING AGGREGATE CRUSHING VALUE. Sep 18, 2017 · AGGREGATE CRUSHING VALUE (IS2386-PART 4-1963) OBJECTIVE. For determination of the aggregate crushing value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. REFERENCE STANDARD.

journal of engineering and technology (jet), vol.6 &2, pp.126-131. relationship between aggregate crushing value (acv) and ten percent fines value (tfv) for nigerian aggregates

The usual size of aggregate used in no fines concrete is 10 to 20 mm. However 5% over size and 10% under size is permissible, but no material should be smaller than 5 mm. A no fines concrete having a low density of the order of 640 kg/m 3 can be produced by using light weight aggregate.

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals. ...
