How does Corrosion Impact Concrete Construction and How to Counter it?

Among the many challenges faced by engineers and architects, corrosion of RCC elements, particularly Structural Steel has been the prime hindrance in deriving long-lasting and low-maintenance structures.

While a many might think that corrosion merely effects structural durability, it is a fact that the mechanical and structural properties of building components can directly as well as indirectly be impacted with structural steel corrosion.

Being a construction staple for decades, concrete is a popular choice of building technology that poses advanced advantages. Yet there are a few challenges that need addressing so as to derive the strongest, safest and the best lasting structures.  

Corrosion of Structural Steel    

Steel is the most preferred choice of metal to be used as reinforcement in concrete. But over time, the metal gets more and more susceptible to lose its strength, volume and longevity due to corrosion.

Occurring due to exposure of steel bars to saline water, chlorides and other elements, corrosion and rusting of structural steel is a big negative in construction and can make the entire building lose its strength and safety.

How corrosion impacts building structures?  

The effects of structural steel corrosion deteriorate the load bearing capacity, durability as well as service span of a building. Here is how your building gets effected with corrosion -     

•   Compromised strength  

Structural strength of a building can be severely reduced due to corrosion of structural steel. As the metal gets eaten away, its load bearing is affected and the overall structure loses its strength.

•   Reduced flexibility 

Use of Structural Steel in RCC construction has a prime aim to impart flexibility to the building in order to counter seismic forces as various dynamic loads. Corrosion also impacts this property and makes a building less flexible.   

•      Fatigue  

With corrosion of structural steel, a building structure may suffer from fatigue and this accelerates crack propagation thus compromising the entire structure’s strength. 

How to counter corrosion of Structural Steel in construction?     

Relying on quality materials and opting for the Thermo Mechanically Treated Steel Bars as offered by the Top TMT bar manufacturer Panipat helps alleviate the chances of corrosion and eliminate risks to the structure significantly.

These TMT Bars are manufactured through advanced Temp core technology processes and have been formed of the purest sourced steel resources. They are less prone to corrosion and their minimal vulnerability to rusting helps achieve the desired strength and longevity from buildings.

7 STAR Shri Rathi Group is accoladed to be one of the Top Structural Steel Suppliers in Panipat and has almost two decades of unhindered recognition as the best manufacturer of corrosion resistant thermo mechanically treated structural steel bars.
