Deformed Reinforcement

Definition

Deformed Reinforcement refers to reinforcing bars, bar and rod mats, and deformed wire used in concrete construction. These materials have surface deformations, such as ridges or grooves, that enhance their bond with concrete, improving the strength and stability of the structure.

Purpose

The purpose of deformed reinforcement is to provide additional tensile strength to concrete, which is inherently weak in tension. The deformations on the reinforcement's surface help create a mechanical bond with the concrete, preventing slippage and enhancing the structural integrity of reinforced concrete elements.

Examples of Use

1. Reinforced Concrete Beams: Using deformed reinforcing bars to increase the tensile strength and load-bearing capacity of concrete beams in buildings and bridges.
2. Slab Construction: Incorporating deformed wire mats in concrete slabs to control cracking and improve the overall durability of the floor or pavement.
3. Column Reinforcement: Adding deformed bars in concrete columns to support vertical loads and prevent buckling under compression.

Related Terms

• Rebar (Reinforcing Bar): Steel bars or mesh of steel wires used as a tension device in reinforced concrete and masonry structures.
• Concrete Reinforcement: The process of adding materials like steel bars, wire mesh, or fibers to concrete to enhance its strength and durability.
• Bond Strength: The measure of adhesion between reinforcing materials and concrete.

Notes

• The deformations on reinforcing bars are standardized to ensure consistent performance and bonding with concrete.
• Proper placement and securing of deformed reinforcement are crucial to achieve the desired structural benefits.
• Various sizes and grades of deformed reinforcement are available to suit different construction requirements.
