Which outcome occurs when a reinforced concrete beam experiences alkali-silica reaction (ASR)?

💡 Explanation

When ASR happens in a concrete beam, silica reacts with alkalis from the cement, forming a gel that expands with moisture absorption, causing internal cracking and reducing concrete strength and load carrying capacity. Therefore, load capacity decreases, rather than increased ductility, enhanced bonding or steel passivation require different chemical processes or mechanical properties.
