Answer Posted / santosh singh
TMT steel bar is a newer variety of steel for construction purpose. Earlier people have been using TOR Steel for concrete reinforcement.
Thermo Mechanically Treated bars (TMT bars) give you several advantages over the other types of steel:
Twisting operation is not involved in the production of the TMT steel bar,so no residual stresses involved in that , which in turn increases the corrosion resistance.
Rust and Corrosion Resistance :
The main reason for failure in any reinforcement concrete structure is due to corrosion of TOR Steel in the concrete, where this steel corrodes in existence of chloride ions. TMT Bars, due to its Thermo- mechanical treatment are very highly rust and corrosion resistant and is best suited in the humid and coastal states like West Bengal and Orissa.
Uses:
TMT Bars are much superior to conventional TOR Steel by virtue of their various engineering properties and can be used for Residential Buildings, Bridges, Drums, Industrial Establishment and all types of concrete reinforcement purposes.
