Minimum spacing between horizontal parallel reinforcements of the same size should not be less than one diameter. However, when compaction takes place, the minimum horizontal spacing is the diameter of the larger bar or 5 mm more than the maximum size of the core aggregate.

Minimum Spacing Between Horizontal Parallel Reinforcement
The minimum spacing between horizontal parallel reinforcement of different sizes should not be less than one diameter of the thicker bar. This is to ensure proper spacing and adequate cover for the reinforcement bars in the concrete structure.
Explanation:
- Spacing Requirement: The spacing between reinforcement bars is critical to ensure the structural integrity of the concrete element. In the case of horizontal parallel reinforcement of different sizes, the minimum spacing should be based on the diameter of the thicker bar to prevent congestion and facilitate proper concrete consolidation.
- Thicker Bar Diameter: Using the diameter of the thicker bar as the basis for spacing ensures that there is enough room between the bars for concrete flow during construction. This helps in achieving a compact and well-consolidated concrete structure.
- Preventing Interference: Maintaining a minimum spacing of one diameter of the thicker bar between horizontal parallel reinforcement bars also helps in preventing interference during concrete placement and compaction. It allows the concrete to flow freely around the bars and reduces the risk of voids or honeycombs in the structure.
- Structural Performance: Adequate spacing between reinforcement bars is essential for ensuring the structural performance and durability of the concrete element. Proper spacing helps in distributing the loads effectively and enhancing the overall strength of the structure.
Therefore, it is important to adhere to the minimum spacing requirement of one diameter of the thicker bar when placing horizontal parallel reinforcement of different sizes in concrete structures.
