Which outcome occurs when grout volume is insufficient during post-tensioned concrete stressing?

💡 Explanation

Insufficient grout exposes the prestressing steel to corrosive agents if complete encapsulation isn't achieved. Corrosion accelerates because the electrochemical potential difference can develop on the steel’s surface regions; therefore, the risk rises rather than strength increasing, which proper grouting assures.
