Which of the following is not a type of reinforcement splicing?

In the context of reinforcement splicing, the concept focuses on methods used to connect two pieces of reinforcing steel (rebar) in construction. Each method has different implications for the integrity and strength of the resulting structure.

Lapping, welded, and mechanical coupling are all recognized methods of splicing rebar, where the goal is to create a reliable joint that maintains the load-carrying capacity of the reinforcement.

Lapping involves overlapping the ends of two rebar pieces for a specified length, allowing for the transfer of forces between them. Welded connections involve using heat to fuse the rebar ends together, providing a continuous piece that can resist tension and shear forces. Mechanical coupling refers to the use of a mechanical device to connect the ends of rebar, ensuring a strong bond without requiring welds or overlaps.

On the other hand, bonding generally refers to the adhesion between materials rather than a specific method of splicing rebar. While bonding is essential in the context of concrete and rebar interaction, it does not fall into the category of methods explicitly used to splice rebar itself. Therefore, it is not considered a type of reinforcement splicing, setting it apart from the other methods listed.
