Question

Concrete cover is the minimum distance from the _________.

1) Center of the reinforcing bar to face of concrete
2) Outside of the reinforcing bar to face of concrete
3) Center of the bar to the edge of an adjacent bar
4) Edge of the deformation lines to the center of the bar

Answer 1

The concrete cover is the minimum distance between the center of the reinforcing bar and the face of the concrete.

Step-by-step explanation:

The correct answer is 1) Center of the reinforcing bar to face of concrete.

Concrete cover is the minimum distance between the center of the reinforcing bar and the face of the concrete. It is an important parameter in civil engineering and construction, as it helps protect the reinforcing bar from corrosion and provides structural integrity to the concrete. For example, in reinforced concrete beams or columns, the concrete cover ensures that the reinforcement is adequately protected from environmental factors such as moisture and chemicals.

Having a sufficient concrete cover is crucial for maintaining the durability and safety of reinforced concrete structures.
