Question

Per §5.4.3, in the Compacting Factor Test the compacting factor is computed as:

Accepted Answer

C. {'text': 'Compacting factor = D divided by E', 'label': 'C'}

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.

Answer

{'text': 'Compacting factor = E divided by D', 'label': 'A'}

Answer

{'text': 'Compacting factor = D plus E', 'label': 'B'}

Answer

{'text': 'Compacting factor = D minus E', 'label': 'D'}
