Which of the following is not a characteristic of deformed rebar?

Deformed rebar is specifically designed for use in reinforced concrete to enhance the bond between the rebar and the surrounding concrete. Its surface features, such as ridges and indentations, improve anchorage by providing mechanical interlock, which ultimately results in better structural performance. This characteristic of improving the bond with concrete is paramount in ensuring the strength and durability of concrete structures.

Another key attribute of deformed rebar is its greater tensile strength compared to smooth bars. The deformations allow it to withstand higher loads without failure, which is a critical consideration in structural applications.

Deformed rebar also comes in standardized sizes, ensuring consistency and compatibility across various construction projects. This standardization is essential for industry practices, making it easier for contractors and engineers to work with rebar.

In contrast, a smooth finish is not a characteristic of deformed rebar. Smooth rebar, although it may be used in specific applications, does not offer the same benefits of improved bonding with concrete that deformed rebar does. It lacks the surface modifications that contribute to better structural integrity when embedded in concrete. Thus, the option mentioning a smooth finish stands out as it does not apply to deformed rebar, which is inherently designed to have a rough texture to enhance
