After manifesting research, it was concluded that the reason behind corrosion or oxidation of the rebars was its contact with chloride from water and deicing salt from the structure. It was inevitable for carbon steel rebars to easily corrode and rust from chloride and salt. Because of rust formation inside the structure, a brute force is created that exceeds the ductile strength of the concrete and hence, it result in cracking and crumbling of the building.
In order to address this situation, researchers started to work of the following strategies:
I.Develop dense cement concrete that prevent chloride and salt from entering the structure.
II.Create special coating for the concrete structure itself.
III.Confine corrosion with cathodic protection or chemical compound.
IV.Build non-metallic rebars.
V.Develop high corrosive resistant metal rebar.
After eliminating the expensive and unfeasible strategies, the researchers chose the fifth strategy of developing a high corrosive resistant metal rebar.
The only inexpensive and high corrosive resistance metal available in the market today was stainless steel. Stainless steel rebars were started to manufacture and they proved to be high corrosion resistant, which also had good strength and better ductile properties. Besides, they also had good high and low temperature mechanical properties, which made them ideal for any weather condition. These stainless steel reinforcing bar definitely cut down the life cycle costs for various buildings and structures.
