Answer- D. Workability
The compacting factor test of cement concrete determines its Workability.
Solution
Workability of concrete can be measured using slump, compaction factor and Vee bee time. The compacting factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete.
Degree of Workability | Compaction factor | Use for which concrete is suitable |
Very low | 0.78-0.80 | Vibrated concrete for pavement road |
Low | 0.80-0.85 | Mass concrete foundation without vibration |
Medium | 0.85-0.92 | Less workable, flat slabs, manually compacted reinforced concrete |
High | 0.92-1.00 | Highly reinforced concrete |
