A70 to 80 percent of the volume
B40 to 50 percent of the volume
C20 to 30 percent of the volume
DMore than 90 percent of the volume
Answer & Solution
Correct answer: A. 70 to 80 percent of the volume
1. §2.1 reads: 'aggregates… give body to the concrete and occupy 70 to 80 percent of volume of concrete.'
2. §2.4 summary repeats: 'aggregates form about 70 percent of the concrete.'
3. Hence the dominant volume share lies between 70-80 percent.
