Per §5.4.3, in the Compacting Factor Test the compacting factor is computed as:
ACompacting factor = E divided by D
BCompacting factor = D plus E
CCompacting factor = D divided by E
DCompacting factor = D minus E
Answer & Solution
Correct answer: C. Compacting factor = D divided by E
1. §5.4.3: 'Compaction factor = D/E', where D = weight of partially compacted concrete (after free fall through both hoppers into the cylinder) and E = weight of fully compacted concrete (cylinder refilled and rammed).
2. Hence a mix with higher workability will have a higher compacting factor.
