Which of the following terms refers to a type of steel reinforcement in concrete slabs?

Steelbar
Bottom plate
Rebar
Top plate

The correct answer is: Rebar

The term that refers to a type of steel reinforcement in concrete slabs is "Rebar." Rebar, or reinforcing bar, consists of a grid of steel rods that are embedded within the concrete to improve its tensile strength and overall durability. Concrete is strong in compression but weak in tension; therefore, rebar is essential to help the structure withstand tensile forces, preventing cracks and failure. Rebar comes in various sizes and grades, and it is placed in specific configurations depending on the load requirements and the design of the concrete element. In practice, rebar can significantly enhance the structural integrity of concrete slabs, making it a critical component in construction. The other terms do not correctly identify steel reinforcement for concrete slabs. "Steelbar" is a general term that does not specify the type of reinforcement. "Bottom plate" and "Top plate" refer to elements used in wood framing, not steel reinforcement in concrete.
