How To Construct A Corrosion Resistant Building in Central India

To understand how to make a building or structure resistant to corrosion, you have to first understand how corrosion happens and its impact on the structure.

How Do RCC Structures Corrode?

In a concrete building, the corrosion hits the steel parts of the structure. As we know, rust occurs when iron or an iron alloy (such as steel) is exposed to moisture or oxygen for a sustained duration.

How Earthquake Resistant TMT Bars Prevent Structural Damage

Several parts of India are excessively earthquake-prone. In fact, the past few big earthquakes in the country (like the ones in Latur in 1993, Bhuj in 2001 and Kashmir in 2005) have been seared in our collective memories as incredibly tragic events.

Effects of Corrosion on TMT Bars and Building Structure

Corrosion of RCC structures is an on-going challenge for the whole construction industry. Every year the government spends millions in the maintenance of civil structures across the country. And almost all of it is to battle structural deterioration – of which corrosion is one of the main culprits!

TMT Bars Come In Many Varieties – Find Out Which One Best Fits Your Needs

TMT or Thermo-Mechanically Treated bars are the backbone of the modern construction industry – from simple homes to skyscrapers to bridges and underwater structures – no matter what is being constructed, dig a little, and you are bound to find TMT bars inside every concrete structure.

Earthquake Resistant TMT bars for central India’s seismic zones

It has been found that the most differentiating factor to survive earthquakes with least damage is the use of high-quality TMT bars which should stick to minimum requirements defined in IS 1786-2008.

Based on scientific inputs for seismicity, earthquakes in the past and tectonic setup of the region, Bureau of Indian Standards (BIS) defined four seismic zones which mapping intensity levels of earthquakes:

Cities / towns in India majorly fall under Seismic Zones III, IV and V; and hence an increased focus on earthquake resistant construction in the country is need of the hour.

• Zone V: The areas under zone V are most vulnerable to earthquakes; Entire northeastern India, parts of Jammu and Kashmir, Himachal Pradesh, Uttaranchal, Rann of Kutch in Gujarat, part of North Bihar and Andaman & Nicobar Islands. Read more...

Thermo Mechanically Treated Bars & Different Sariya Grades

Thermo Mechanically Treated Bars (TMT bars) are manufactured by treating them thermally through quenching, heating and finally compressing to form bars.
Quenching refers to a heat treatment in a quenching box where rebars are rapidly cooled using a special water spray system. This hardens the surface of TMT bar while the core still remains hot and soft. After quenching of the bar, self-tempering happens during which the heated core of the bar supplies heat to outer martensitic surface making tempered martensite. Post tempering, atmospheric cooling is done on cooling beds to get the ductile ferrite-pearlite structure of the core. 
Moira TMT bars are manufactured using the latest German “Thermex” technology. This technology involves exposing bars to temperature as high as 1100 degree Celsius, then passing through rolling mills and finally through high-pressure water which makes these bars cool outside and still heated at core inside on account of thermal exchange. This provides Moira TMT bar the characteristic property of having an inner soft core and a tougher outer core.
The grade of Steel is an important factor which governs the strength and durability of TMT bars. Moira TMT bars are high-quality bars using Fe-500, Fe-500 D, Fe-550, and Fe-550 D grades as per IS Code. Our bars are ranging from 8mm to 40mm diameter offering a wide variety as per the need and type to construction. Read more...

Tips for Cost Saving while buying TMT Bars

Using TMT bars of Fe-500 grade instead of Fe-415 grade leads to up to 20% savings on material thus leading to a saving in the amount spent on buying TMT bars. The difference in the strength between Fe-415 and Fe-500 grades is 20%, Fe-500 being 20% stronger than Fe-415. The reason for this is as follows:

– Fe-415 denotes that a force of 415 N/sq.mm. is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar.
– The difference in the strength between Fe-415 and Fe-500 grades therefore is 20%.

This gives Fe-500 a superior structural strength than Fe-415 and therefore lesser number of Fe-500 TMT bars are required to hold the structure as compared to Fe-415. Read more...

Importance of Using Corrosion Resistant TMT

Corrosion refers to the damage caused by oxidization or by other chemical reactions on the surface/body of any substance (especially a metal). Withstanding this damage indicates a good corrosive resistance.

A Corrosion resistant rebar with a reduced rate of corrosion enhances total life of the structure from the time of construction.TMT bars carry a huge load of a complete structure and protect it against cracking. Hence are in forcing bar with improved corrosion resistance over traditional carbon steel reinforcing bar is definitely a better choice.

The advantages of Corrosion resistant TMT rebars over normal steel reinforcement bars being:

• Longer life against ordinary bars.
• Higher ductility and bending capacity.
• Easily Weld-able.
• More reliability in extreme conditions like groundwater salinity, acid particles in the air etc.
• Higher yield strength and hence can be used in seismic activity zones.
• Usable in construction along sewage drains and sewage treatment plants against the steel bar which has more chances to get damaged due to salts or acids or bases in sewage read more...

Why we need TMT bars?

TMT Bars hold extreme importance in new age construction; it can be houses, bridges, buildings or any construction structure. These bars offer durability, age and strength to the construction by its unique set of properties. The high strength which these bars offer to the building enables it to withstand stress. The various properties of seismic resistance, anti-corrosion, shock absorbing ability and high tensile strength guards the building from natural calamities and makes it a safer construction which lasts longer.

  Moira TMT Bars are hardened by a thermo mechanical process. The process involves passing steel    through a water cooling system after they pass through the last rolling mill. With this process, the bar is softened at the inner side/layer and hardened at the outer side/layer. This also enables the bars with greater bendability and strength which makes it easier to shape or mould them as per the need of construction. This makes Moira TMT Bars best fit for use in buildings and concrete structures read more...
