A4.75 mm
B150 micron (0.150 mm)
C2.36 mm
D75 micron (0.075 mm)
Answer & Solution
Correct answer: A. 4.75 mm
1. §2.2.3: 'Coarse Aggregate - size greater than 4.75 mm. Fine Aggregate - size less than 4.75 mm.'
2. Table 2.6 then reinforces the boundary by placing 4.75 mm at the bottom of the coarse aggregate column and the top of the fine aggregate column.
