Placing reinforcement begins with pouring of concrete.

• A. False
• B. True
• C. It depends
• D. Always

Answer: (A)

Reinforcement is placed before the concrete is poured to ensure the steel is properly embedded, spaced, and secured so it can bond with the concrete and provide the intended strength and crack control. In tilt-up construction, you lay out the rebar or other reinforcement according to the drawings, set chairs or spacers to maintain the required concrete cover, and tie or weld connections as specified, then you inspect and approve this setup before any concrete is poured. Pouring without the reinforcement would leave the concrete unsupported by the steel, compromising structural capacity and crack control, and you would not achieve the designed bond and load transfer. Post-tensioning or other forms of prestressing are separate steps that occur after the concrete has cured, but they do not replace the need to place reinforcement prior to the pour.
