Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. 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%). TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.
with an aggregate crushing value higher than30, and in such cases the method for ten per cent fines value described in BS 812-111 is applicable. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS 812 the definitions given in BS 812-100, BS BS 812 Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete. For crushing values of over 25 to 30, the test is insensitive because the weaker material is crushed before the 400 kN load is reached and compacted in a manner that further crushing is reduced. For such materials, a ten percent fines value test is suggested by BS812, Part 3.

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 812-1975). The analysis of experimental and published aggregate test results indicate that the fines versus load relation of aggregates is linear and has a varying intercept and slope in the fines versus load diagram. 59 kg aggregate crushing value (acv) ten pecent fines value (tfv) bs 812 standard test A 257/01 A 257/02 AT 211/P AA 525 241 tecnotest geometric properties 2.3.1 los angeles abrasion machine D 504 astm c 131 cnr 34 en 1097-2 Used to measure the resistance of aggregates to abrasion.
The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,29,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS Method 842. 3 METHOD Follow SABS Method 842. 4 CALCULATIONS 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.
