Question: 1 / 400

What is the purpose of using wire ties in rebar installation?

To prevent rusting of the steel

To secure rebar in place during concrete pouring

The purpose of using wire ties in rebar installation primarily revolves around securing the rebar in place during the pouring of concrete. This is critical to ensure that the reinforcement remains in the correct position, maintaining the appropriate spacing and alignment as specified in the project design. Proper placement of rebar is essential for the structure's strength and stability, as it helps to control cracking and prevent structural failure.

When wire ties are used, they create a strong connection between rebar bars, ensuring that they do not shift or move while concrete is poured over them. This is crucial because any displacement could compromise the integrity of the reinforced concrete structure. The ties are designed to be sturdy yet easily manipulated, allowing workers to efficiently and effectively secure the rebar before the concrete is introduced.

In contrast, the other choices highlight misconceptions about the role of wire ties. While preventing rusting is important for the longevity of rebar, wire ties do not serve this purpose. Adding weight or enhancing the decorative aspect of the rebar are not functions of wire ties, which are strictly utilitarian in nature during the rebar installation process.
