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.
