In a compaction factor test of concrete, if the compaction value is less than 0.95 and greater than 0.85, then
the standard of the workabilty is:
-
A.
Very good
-
B.
Fair
-
C.
Medium
-
D.
Good
Correct Answer:
C. Medium
Explanation:
In a compaction factor test, a value between 0.85 and 0.95 indicates Medium workability. This test measures the ratio of the weight of partially compacted concrete to fully compacted concrete, providing a numerical value for consistency. A factor in this specific range represents a plastic mix that is suitable for normal reinforced concrete work where vibration is used for compaction. Values below 0.85 signify low or very low workability, while values above 0.95 represent high workability for flowing concrete.
