Cylindrical Concrete Cover Blocks (with tie wire)
Used to maintain the required clear cover between reinforcement bars and formwork.
Typical features in your photo:
• Cylindrical shape → commonly used for slabs, beams, columns.
• Metal wire loop → tied to rebar to keep the spacer from shifting.
• Cast from regular or high-strength concrete → matches strength of the structural concrete.

Common Types of Concrete Cover Blocks

1. Plain Cube / Square Cover Blocks
2. Cylindrical Cover Blocks with Tie Wire
3. Circular / Wheel Spacers
4. Rebar Chairs (plastic or concrete)
