Workability of concrete and Compaction factor test ...

Sep 11, 2017  Any surplus concrete from the cylinder is removed in the manner explained before. The weight W 2 of the concrete in the cylinder is found out. The ratio of the two weights W 1 /W 2 is known as the compaction factor. A compaction factor of 0.85 represents a mix of poor workability, 0.92 represents medium and 0.95 good workability.
