Answer 1

The correct option is (b) only the concrete is interrupted

Best explanation: A complete contraction joint is the one in which both the concrete and reinforcing steel is interrupted. A partial contraction is the one in which only the concrete is interrupted the reinforcing steel running through. A distinction should also be made between them.
