Which outcome occurs when thermal gradients impose stress on pre-stressed concrete?

💡 Explanation

Increased tensile crack propagation occurs because uneven expansion caused by the thermal gradients weakens the concrete, exceeding the compressive force applied by pre-stressing causing material failure through **stress corrosion cracking**. Therefore, crack propagation increases, rather than the damping or compaction.
