COMPACTION FACTOR TEST
Find the compaction factor of concrete using the following data: Weight of partially filled concrete with cylinder = 16 kg, Weight of fully compacted concrete only = 13 kg, Weight of empty cylinder = 9 kg
A compaction factor of 0.79 indicates that the workability of concrete mix is:
What is the ratio of slump value in mm to that of compaction factor for the concrete mix for low degree of workability concrete? (Reference: Very Low - 1.25 cm, 0.79 | Low - 5.0 cm, 0.825 | Medium - 7.5 cm, 0.885 | Very High - 12.5 cm, 0.96)
If W be the weight of empty cylinder, W1 be the weight of partially filled concrete only and W2 be the weight of fully compacted concrete with cylinder, then which of the following is the correct formula for finding the compaction factor?
In how many layers the concrete should be manually compacted in the receiver?
