Which outcome develops when anaerobic bacteria metabolize sulfates in concrete?

💡 Explanation

Ettringite formation occurs because biogenic sulfuric acid reacts with aluminates in the cement paste, causing expansion that leads to concrete cracking. Therefore, ettringite causes expansion rather than maintaining passivation, sealing cracks, and hardening the matrix.
