Passive layer of chromium oxide prevents rusting.
To protect the concrete structure from corrosion few techniques have been adopted without much success.
Coatings on the steel bars.
Using Alloy Steel in the place of Carbon Steel.
Cathodic Protection
Addition of lnhibitors in the concrete.
Increase concrete cover thickness.
Reduced water /cement ratios
Though application of coatings to rebar is an easy route, damage of coatings during handling is the main limitation. Effect of inhibitors is temporary and short-lived. Cathodic protection is perhaps the perfect method but is difficult to implement and requires post maintenance and monitoring (Stainless steel is therefore the only solution for enhancing corrosion protection of concrete).
Low alloy steel with alloy concentration – 1% or so are also not the answer, where the concrete is exposed to both high levels of urban pollution and aggressive marine environment.
What Type Of Stainless Steel Can Be Used In The
Reinforcement Of Concrete?
A wide range of stainless steel alloy types is available for rebar selection, to meet the mechanical design aspects and the expected corrosivity of the environment. Stainless Steels are available mainly in five main groups. Austenitic, Ferritic, Duplex, Martensite and Precipitation hardened steels. Depending upon several factors such as relative corrsion, longevity, life cycle cost the SS REBAR GRADE G Stainless Steel is a desirable material. SS REBAR GRADE G is currently used by Orbit Buildcon & Reality [P] Ltd. in Mumbai for their premium housing projects. Orbit Buildcon is a famous construction company located in Mumbai.
