Minimum cross sectional area of longitudinal reinforcement in a column is 0.8%.

Spacing of longitudinal bars measured along the periphery of column should not exceed 300 mm.

Reinforcing bars in a column should not be less than 12 mm in diameter.

The number of longitudinal bars provided in a circular column should not be less than four.

Higher Vee-Bee time shows lower workability.

Higher slump shows higher workability.

Higher compacting factor shows higher workability.
