The aggregate impact value is expressed as the percentage of the fines formed w.r.t the total weight of the sample Aggregate Impact Value (AIV) = (100*M2)/M1 Where: M1 =Mass of the test specimen M2 = Mass of the test specimen passing 2.36 mm test sieveThe 10 % Fines Value (TFV) is determined by measuring the load required to crush a prepared aggregate sample to give 10 % material passing a specified sieve after crushing. The test is also known as the 10% Fines Aggregate Crushing Test - 10 % FACT. The test can be performed in both a dry condition and in a soaked condit-ion.Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
Here are the recommended Aggregate Impact Test values and their corresponding classifications: Aggregate Impact Value Classification. Less than 20%: Exceptionally strong. Between 10% and 20%: Strong. Between 20% and 30%: Satisfactory for road surfacing. More than 35%: Weak for road surfacing.This Product Manual shall be used as reference material by all Regional/Branch Offices & licensees to ensure coherence of practice and transparency in operation of certification under . 4 Aggregate impact value - Impact testing machine [Clause 4.2 (a) and Fig 2 of (Clause 5.4.2) IS 2386 (Part 4) : 1963]-IS sieves -12.5 mm, 10 mm & 2.36 mm
