Which failure outcome in reinforced concrete elevated slabs results due to Alkali-Silica Reaction (ASR) combined with insufficient rebar cover?

💡 Explanation

Expansive cracking and spalling occur because, the ASR reaction generates swelling pressure accelerating concrete degradation. The concrete's limited tensile strength results in cracking due to hoop stress, therefore cracking and spalling, rather than purely elastic or shear failure, occur under concurrent ASR and insufficient rebar cover.
