The grading of an aggregate is found by passing a representative sample of dry aggregate through a series of sieves, starting with the largest mesh. The size of the sample tested depends upon the maximum size of the aggregate. For nominal 40 mm aggregate the sample should weigh at least 5 kg, for 20 mm at least 2 kg, for 10 mm at least 0.5
