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 - The main processes that cause the deterioration of concrete include carbonation and chlorination which occurs due to corrosion of reinforcement and other causes are alkali-silica reaction, loss of oxygen and cracking of concrete. Hence, corrosion in reinforcement structure affects structural durability due to chlorination and carbonation.
A. The main processes that cause the deterioration of concrete include carbonation and chlorination which occurs due to corrosion of reinforcement and other causes are alkali-silica reaction, loss of oxygen and cracking of concrete. Hence, corrosion in reinforcement structure affects structural durability due to chlorination and carbonation.

Explanations:

The main processes that cause the deterioration of concrete include carbonation and chlorination which occurs due to corrosion of reinforcement and other causes are alkali-silica reaction, loss of oxygen and cracking of concrete. Hence, corrosion in reinforcement structure affects structural durability due to chlorination and carbonation.
