the aggregate crushing value (acv) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kn. 2 apparatus 2.1 an
calculation of aggregate crushing value. the aggregate crushing value is defined as the ratio of the weight of fines passing through specified is (here 2.36mm sieve) to the total weight of sample expressed in percentage. w1= weigh of the total aggregates (wa-we) w2= weigh of aggregates passing through 2.36mm is sieve.
procedure of aggregate crushing value test:-. sieve the test material through 12.5 mm and 10.0 mm is sieve. take test samples of aggregates passing through 12.5 mm is sieve and retained on 10 mm is sieve (minimum 3 kg). dry theme in an oven for 4 hours at a temperature of 100 °c to 110 °c and then cool at room temperature.
q.3) a sieve analysis was carried out for 5 kg aggregate in the laboratory with available sieves. the weights retained in sieve of 40,32,20,16,10,4.75,are 0,1.2,1.8,0.5,1.5and 0 kg respectively. obtain fineness modules for the sample.
the crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. the percentage of weight passed through the 2.36m is sieve is known as aggregate crushing value.. in situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined
