Which consequence results when a prestressed concrete beam experiences aggregate degradation?

💡 Explanation

Reduced load-bearing capacity occurs because **alkali-aggregate reaction** causes expansion and cracking within the concrete matrix, weakening bond to steel rather than improving material properties; therefore, the beam fails prematurely, rather than exhibiting enhanced ductility or insulation.
