Q: Minimum spacing between horizontal parallel reinforcement of the same size should not be less than
  • A. one diameter
  • B. 2.5 diameters
  • C. 3 diameters
  • D. 3.5 diameters
Correct Answer: Option A - The minimum spacing between horizontal parallel reinforcements of the same size should not be less than one diameter or bars use different diameter, should not be less than one dia of thicker bar. • However, when a compaction takes place, the minimum horizontal spacing is the diameter of the larger bar or 5mm more than the maximum size of the coarse aggregate.
