degradation of concrete causes and solutions

• DEGRADATION
• OF REINFORCED CONCRETE
• CAUSES SOLUTIONS

INTRODCTION

• The corrosion of steel in concrete structures
  such as bridges, roads, buildings, dams, etc. is
  a world wide phenomena that leads to structural
  weakness and degradation.

CORROSION

• For steel reinforcement to corrode, the passive
  oxide layer on the steel must fail. If the
  concrete cover that protects the reinforcing
  steel is damaged and the bond between the
  concrete and steel reinforcing bar is
  ineffective, the steel s passive layer will
  break down and active corrosion of the steel will
  occur.

• Concrete is more widely used than any other
  manmade material and has been a construction
  staple for centuries.

SALT-INDUCED CORROSION

• Chloride-induced corrosion is the single largest
  problem for aging concrete highway bridges,
  particularly in marine environments or areas
  where road salts are used.

GFRP COMPOSITES

• GFRP composite, for instance fiberglass rebar,
  materials are rust-free thus protect concrete
  structures against severe environment.
