Q: Corrosion in reinforced concrete structures affects the structural durability due to :
- A. chlorination and carbonation
- B. poor aggregate quality
- C. poor concrete compaction
- D. less cement content
Correct Answer:
Option A - Concrete carbonation causes embedded steel reinforcements to corrode, with the resulting expansion cracking and weakening the concrete.
• Chloride attack concrete deteriorates the durability of concrete by initiating the corrosion of the reinforcement, which may cause the failure of the structure.
