2. Three samples of aggregates are sieved to obtain the grading curve. A set of different sieves is stacked with the coarsest mesh at the top. The aggregate is then placed in the top sieve and the stack is placed in a sieve shaker. The raw data is as follows: Sieve size (mm) 19 9.5 4.75 2.36 1.18 0.6 0.3 0.15 Pan Mass of sieve (g) 670 620 620 570 570 520 520 520 490 Mass of sieve + aggregates retained (g) Sample B Sample A 670 770 820 740 720 770 720 570 525 670 1820 620 570 570 670 720 620 544 Sample C 670 620 620 670 770 720 620 620 506
