Difference Between Ten Percent Fines Value Of Aggregates And Aggregate Crushing Value May 08, 2013 Objective For determination of the aggregates 10% fines value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm IS sieve Reference Standards IS : 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properties.
Based on this assumption, they proposed a means of estimating the ten per cent fines load of aggregate from the crushing test. This method was also accepted by the British Standards (BS …
Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement Construction
2012/02/08· 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% (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.
Ten percent fines value is defined as the load taken by the soaked sample at ten percent of fines. APPARATUS. Standard Compression Testing Machine. A cylindrical metal measure having an …

Difference Between Ten Percent Fines Value Of Aggregates And Aggregate Crushing Value May 08, 2013 Objective For determination of the aggregates 10% fines value of coarse aggregate, …
The ten percent fine value test shows a fairly good correlation with the standard crushing value test for strong aggregates, while for weaker aggregates the ten percent fines value test is …
Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing …
RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE (ACV) AND TEN PERCENT FINES VALUE (TFV) FOR NIGERIAN AGGREGATES. This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some …
According to Uche and Muhammad (2011), ACV of a concrete aggregate should not exceed 30%. The granite, PKS and PS had an …
ten fines value aggregate crushing value difference. The Page Description. What is the significance of ten percent fines value in,- 10 fines crushing value limits,The test aims at looking for the forces required to produce 10 of fine values ie weight of fines aggregates/weight of all aggregates = 10 This test is very similar to Aggregate Crushing Test in which a standard force …
Ten percent fines value is defined as the load taken by the soaked sample at ten percent of fines. APPARATUS. Standard Compression Testing Machine. A cylindrical metal measure having an internal diameter of 57 ± 1 mm and an internal depth of 90 ± 1mm; Steel cylinder open ended with plunger and base plate with a normal internal diameter of 75mm
The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag, hoggin (all-in aggregate), and river gravel respectively. This show that the ACV test is not favourable in testing weak aggregates as the ACV is more than 30% for hoggin and river aggregates.

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100 Lab Report
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. …

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular sub-base is subjected to repeated …
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 ten percent fine value test shows a fairly good correlation with the standard crushing value test for strong aggregates, while for weaker aggregates the ten percent fines value test is more sensitive and gives a truer picture of differences between more or less weak aggregates.
