alleryStart learning →For ordinary reinforced concrete work, the source recommends a maximum aggregate size of:
A10 mm
B20 mm
C40 mm
D80 mm
Answer & Solution
Correct answer: B. 20 mm
1. §2.2.3 reads: 'keeping in view all practical consideration, for reinforced concrete work a maximum aggregate size of 20 mm is considered satisfactory.'
2. The general convenient maximum is 80 mm, but it is restricted by member thickness, reinforcement spacing and clear cover.
