#8 Rebar — Size, Weight, Use-Cases and More

#8 rebar is commonly used in concrete construction for various applications where substantial reinforcement is required. Some typical uses include:

1. Structural Beams and Columns: Utilized to reinforce structural beams, columns, and other load-bearing elements in buildings, bridges, and other structures to enhance strength and resist bending.
2. Foundation Slabs: Employed in the construction of foundation slabs for residential, commercial, and industrial buildings to provide structural support and stability.
3. Retaining Walls: Utilized in the construction of retaining walls to strengthen the structure and prevent soil erosion or collapse, especially in larger and taller walls.
4. Parking Structures: Used in the construction of parking garages and parking lots to reinforce concrete floors, ramps, and decks subjected to heavy vehicle loads.
5. Bridge Decks: Incorporated into bridge decks and highway structures to reinforce the concrete and ensure durability and longevity under heavy traffic loads.
6. Water and Wastewater Structures: Employed in the construction of water treatment plants, wastewater treatment facilities, and storage tanks to provide reinforcement in concrete structures subjected to environmental conditions and water pressure.
7. High-Rise Buildings: Used in the construction of high-rise buildings to reinforce concrete elements such as shear walls, cores, and slabs to withstand vertical and lateral loads.

Overall, #8 rebar is suitable for a wide range of construction projects requiring substantial reinforcement in concrete structures subjected to heavy loads and structural demands.

A #8 rebar (rebar size 8) has the following specifications:

• Diameter: 1 inch (or 1.000 inches)
• Metric Equivalent Diameter: 25.4 mm

The number "8" in #8 rebar indicates that it is 8/8 inch in diameter, which simplifies to 1 inch. This sizing convention helps in quickly identifying the rebar size based on its number designation.

To determine the weight of #8 rebar per foot, you can refer to standard industry weights for rebar sizes:

• Diameter: 1 inch
• Weight: 2.67 pounds per foot, or 3.982 kilograms per meter

This means that if you have a length of #8 rebar, you can calculate its weight by multiplying the length in feet by 2.67 pounds per foot.

An Example

For a 10-foot length of #8 rebar:

Weight = 10 feet × 2.67 pounds per foot = 26.7 pounds

This weight calculation is helpful for estimating the total weight of rebar needed for a project or for making sure you’re compliant with structural design specifications.
