I NTRODUCTION AND THEORY The aggregate crushing value provides a comparative assessment of an aggregate's resistance to crushing under a progressively increasing compressive stress If the aggregate crushing value is 30% or higher, the result may be anomalous and, in such cases, the 10% fines should be determined instead[Step4 : Weigh the container full of aggregate Step5 : Calculate the net mass of aggregate in the measuring cylinder to an accurate of 1 gram This quantity of aggregate constitutes the test specimen Step6 : Transfer the whole of this weighed specimen to the test mould by filling it in three layers as explained in Step2Aggregate Crushing Value Test Construction Encyclopedia
