Many studies have elaborated the impact on structures due to global warming and their exposure to corrosion.
New Delhi: India is the seventh-largest country in the world, with a total area of 3,287,263 square kilometres (1,269,219 sq mi). It has a land frontier of 15,200 km (9,445 mi) and importantly a coastline of 7,516.6 km (4,671 mi).
This is just an indication of how much India is exposed to global warming which is set to severely impact buildings, dams, roads, bridges, automobile sector, railway sector, energy sector and petroleum sector.
climate change is one of the most important concerns for world governments and is a major research subject for the scientific international community with the participation of multi and interdisciplinary groups. Two fundamental reports – the United Nations Intergovernmental Panel on Climate Change (IPCC) and the N. Stern, The Economics of Climate Change, 2007 Cambridge University Press, UK, outlines parameters that will affect infrastructure, temperature change, atmospheric moisture change, sea level raise, wind, desertification, pollution and inclusive biological infestation.
Temperature change is gradually resulting in extreme climate, changing the periodicity of climate cycles. Such extreme climate events are bringing detrimental effect by way of corrosion and also bio-deterioration. This is also damaging both metallic and non-metallic materials used in infrastructure construction.
Many studies have elaborated the impact on structures due to global warming and their exposure to corrosion.
Reinforced concrete (RC) structures are subjected to environment actions affecting their performance, serviceability and safety. Among these actions, chloride ingress and carbonation lead to corrosion of reinforcing bars that reduce the service life of RC structures. Evidence indicate that carbonation and chloride ingress are highly influenced by environmental and climatic conditions of the surrounding environment – atmospheric Co2 concentration, temperature and humidity.
Zinc, through galvanization process, protects steel from rusting that enhances the lives of buildings, houses, bridges, railways, ships, defence equipment, highways, and airstrips to name prominently, though there are a number of other usages of Zinc that protect steel from rusting.
Sunil Duggal said, “Awareness is the key to build a galvanized Indian economy. People do not understand the difference between ‘steel’ and ‘galvanized steel’. Galvanized steel increases the life of steel and gives life to not just industrial sectors but also house-hold sector. Galvanization is a layer of protection to safeguard steel from rusting. Globally people are understanding that use of galvanized rebars can increase the life of their houses that can withstand many risks. Infrastructure at coastal areas are at the maximum risk due to humidity and constantly changing climate. Galvanized rebars protect pillars and hold construction. Galvanization of steel used in car body enhances the life of vehicle multi-fold – your recurring expenditure on repairs decreases and your safety increases. The new mega infrastructure development that is happening in India today, with the use of steel, should only use galvanized steel for strength and long life.”
Sunil Duggal reminded of the massive cloud burst that happened in Uttarakhand in 2013. He said, “I remember in the year 2013, due to cloudbursts in the state of Uttarakhand, the flash floods in river Ganga and landslides washed away thousands of lives.  The Kedarnath Bridge at Sonprayag was also washed out due to heavy floods. The death toll and destruction was so massive that it left the region devastated. Subsequently, a Bailey bridge (a portable, pre-fabricated, truss bridge) was built by the Border Roads Organisation, limiting the traffic to one way and a maximum load of 12 tonnes at the most. But June 2015 saw more floods and this bridge was also washed away.
Since the Temple is 3500 feet above sea level and is situated in a challenging topography, the construction of a stronger flawless bridge required more than 3 years to build. Further, since the bridge was to be built in such difficult conditions, it would have been impossible to regularly protect or maintain. It was finally decided that the new bridge has to be made of galvanized steel to ensure that it does not collapse.
The galvanized bridge was shipped in containers from the USA, completed and became operational in an incredible 45 days. In the new bridge, all the panel chords, diagonals, verticals, raker, reinforcing cords along with all the structural beam members and flooring were hot dip galvanized. This bridge could have been ‘Made in India’.
He gave another example of Bandra Worli Sea Link. The Bandra Worli Sea Link is the first and the longest sea link bridge in India. It is an 8-lane cable-stayed bridge, spanning about 5600 meters in length and towering to a height of 126 meters. Executed at a cost of Rs.16.5 billion, the material used in the construction project had to meet quality regulations and standards considering an average daily traffic of 37,500 vehicles.
“Infrastructure like bridges are extremely vulnerable to rust and corrosion due to their proximity to marine salts and moisture. One of the rust prevention methods for these structures is to provide a barrier coating by galvanization, galvanization by Zinc” he said.
The quality and reliability of steel wire ropes was a crucial factor in the construction of the bridge since the steel wires are required to support the cable stay bridge. The bridge stands strong with support of high-strength galvanized steel cables, rigorously tested before being put to use. Over Rs.90 million is spent on illuminating the sea link. Many countries came together and decided to build this bridge to ensure that it stands tall in any condition. India, Egypt, China, Canada, Switzerland, Britain, Hong Kong, Thailand, Singapore, Philippines, Indonesia and Serbia deliberated extensively on safety and longer life of Bandra Worli Sea Link Bridge and the importance of using galvanized steel.
Sunil Duggal is of the opinion that in India, for environment protection, government has listed several laws. Many Acts have been passed in Parliament. But what about the damage to environment and economy through rusting and corrosion – “Creation of junk is destruction of environment and economy. Corrosion eats around $600 billion infrastructure a year which is about 6% of GDP” he says.
“Coastal salts can create a corrosive environment for any infrastructure across the world, the reason being humid and saline climate. When steel reinforcement corrodes, the corroded product occupies more than three times the volume of the original steel, exerting great disruptive tensile stress on the surrounding concrete, leading to further cracking, more weather access and further corrosion. According to the American Institute of Architects, it is essential to use hot dip galvanized steel, to make such coastal infrastructure decay resistant” he said.
Speaking about the recurring expenditure being incurred by Indian Railways on changing of rails, fishplates and other infrastructure. The fourth largest rail network in the world, Indian Railways, comprises 125,000 km of track length over a route of 67,312 km. More than 50% of the route is electrified. Indian Railways has about Rs 1.35 Lakh bridges and about 800 are most important.
Sunil Duggal said, “Indian Railways sector is a major concern since rusting and corrosion of the infrastructure is becoming a worry for safety of passengers. Almost all the infrastructure of Indian Railways is exposed to humidity, dust and extreme change in climate. It is already struggling due to huge expanses in replacement and repairing. The annual loss due to pre-replacement of corroded rails is huge about Rs. 440 crore. Many accidents have been attributed to corrosion of “Fish-plates”. Experts have estimated losses of almost 4% of GDP per year on account of corrosion which may be avoided if the railway tracks are galvanized. Corrosion reduces the life of rail to nearly half its expected life.”
Car makers in Europe, North America, Korea and Japan have been using galvanized steel for body panels for decades and provide anti-corrosion and perforation warranties for a minimum of 10 years. More than 60% of the cars in India have surface rust which reduces steel strength and the life of the car.
“Globally the top brands in cars started galvanising various parts of the cars including the body to fight corrosion issues. This brought safety to the cars and protection to the environment and strengthened the economy. By 1987, what became standard was a 10-year perforation and five-year cosmetic warranty from all the North American, European and Japanese automakers for vehicles sold in the North American market. Indian car manufacturers’ use about 3% galvanized steel for domestic market. However, the same Indian car manufacturers use over 70% galvanized steel for the same models which they export to markets in Europe, Asia and Africa, produced from the same stamping and assembly facilities.”
He is of the firm belief that “Indian consumers are not getting it, because they are not demanding for. It is their direct loss.”
“India is producing about 100 million tonnes of steel but surprisingly less than 1% is galvanized, which is just about 8 million tonnes. On the other hand we are importing 1.44 million tonnes of galvanized steel from China, Korea and Japan. We are increasing imports but not producing galvanized steel within the country” Sunil Duggal says.
The global galvanized steel market for the industrial sector was valued at around 56 million tonnes in 2015 and is estimated to grow at a CAGR of about 5% by 2020. America alone produced 4.5 million tonnes of galvanized steel in 2016, which is 30% more than what it produced in 2012. There is a focus for building long lasting infrastructure.
He finally says, “Galvanization of steel will add to Make in India and Sustain in India”. We might be making over-bridges, railways bridges, roads, high-rise buildings, railway tracks, fish plates, metros, electricity networks, ships, and automobiles, and using millions of tonnes of steel. But for how many years are we making them sustain is a point of contention. If our vision is long term, then the infrastructure also needs to sustain even longer.

The country’s ambitious railway line between Jiribam-Imphal in Manipur, which connects the capital of Manipur with the broad gauge network of the country, will be completed by 2020, announced by the project Chief Engineer Sai Baba Ankala here on Monday at GITAM Deemed to be University.

He delivered an expert lecture on “Challenges in Design & Construction of the World’s Tallest Bridge” organised by Institute of Engineers (India), GITAM Student Chapter at Civil Engineering Department.
addressing the students, he said that the project was taken up in 2008 and was declared as National Project with a cost of Rs 13,809 crore. He further informed that three IITs (Kanpur, Roorkee and Guwahati) are also associated with this ambitious Indian Railways project by way of technical support and proof-checking of designs to make the bridge cost-efficient and sustainable.
The chief engineer said that the alignment of the 111 km long Jiribam-Imphal railway line passes through steep rolling hills of the Patkai region which must traverse through a number of deep gorges and over several rivers flowing at low ground levels.
As a result, it has been necessary to construct 52 tunnels and 149 bridges crossing 10 stations to maintain a suitable gradient for efficient operation railway services, he added. He highlighted that as part of the railway project they are constructing a special bridge (bridge no.164) with pillars rising to 141 metres which is the tallest in the world from the point of view of pillar height.
The bridge is also located in seismic zone-v and in view of this we are taking all precautions particularly a site-specific design spectrum had been developed to ensure long-term stability of the bridge.
He said the railway line and the bridge are being built despite several threats from militant outfits operating in the area. The surveillance of the bridge through CCTVs, drone cameras and remote monitoring by several sensors is also being considered to ensure the safety, he added.
He mentioned that the government of India is treating this project strategically to strengthen the trade with ASEAN countries and helpful to military operations and tourism development. He advised the students that bridge engineering is challenging subject if thoroughly understand the related aspects. He also invited the civil engineering students to take part the ongoing project for their project report.
GITAM Institute of Technology Principal Prof K Lakshmiprasad, APSRTC Executive Director Dr Ansari, Civil Engineering department in-charge head Prof M Ramesh and Institute of Engineers (I) GITAM Student Chapter Faculty Advisor Dr PC Kumar participated in the programme.

ABB to enhance power quality for India’s longest freight train network
Tuesday, 25 September, 2018, 08 : 00 AM [IST]
Our Bureau, New Delhi
ABB will play a key role by enhancing the reliability of the Dedicated Freight Corridor (DFC), an ambitious infrastructure development designed to enable the efficient movement of freight containers across the vast geography of India, with an innovative power quality
solution. The system is expected to relieve congestion on commuter routes and drive industrial growth and investments in these regions.
The Power Quality challenge
The Dedicated Freight Corridor Corporation of India Ltd (DFCCIL) expects to transport up to 15,000 tonne of load for long distances and will have a container capacity of 400 units per train, among the highest in the world.
To cope with the volume, DFCCIL has pioneered the operation of double-stack containers on electrified routes in India. The trains will be high-speed, with maximum speed varying between 75kmph and 100kmph.
Such high speeds and variation of loads can affect power consumption patterns, creating significant voltage fluctuations and low power factor that cause power quality issues in the electrical railway traction systems. This could result in equipment malfunction and even downtime.
Power quality issues can also spread through the supply grid, creating a domino effect of disturbances to other users. The potential risk of non-compliance to grid codes can also lead to financial penalties.
An efficient and effective power quality solution
To address this challenge, ABB will supply a step-less Power Quality Compensator – Reactive (PQCR), which helps to regulate and stabilise the power supply when there are dynamic and highly fluctuating loads.
The PQCR will help improve power quality and voltage stability and help comply with grid codes. In addition, ABB will also supply fixed and dynamic reactive power compensation panels at 23 traction sub-stations.
By improving the reliability of the grid and reducing downtime, ABB’s innovative PQCR technology will help DFCCIL optimise the operating costs of its freight network. The solution will be implemented in the western segment of the DFC between Mumbai and Dadri, that covers a distance of over 1,500km.
“We are pleased to support the Indian Railways with our state-of-the-art power quality technology and to contribute to a world class freight rail corridor in the country,” said Giandomenico Rivetti, head of ABB’s high-voltage products business, a part of the company’s Power Grids division.
“This initiative further supports ABB’s commitment to contribute to India’s economic growth with state-of-the-art technology solutions,” he added.
As a pioneering technology leader, ABB offers power quality products and solutions in low-, medium- and high-voltage applications for utility, industrial, infrastructure and transportation sectors.
India’s economy is growing at a rapid pace, among the fastest in the world. The country’s rail transportation network, which extends across 3.3 million sq km and is one of the largest in the world, is a key driver.
Core growth sectors like power, coal, steel and cement depend on the rail network, and the increasing importance of this sector has led to the undertaking of an ambitious project to create a high-density DFC. The DFC, which will be developed by DFCCIL, will run between the four cities known as the Golden Quadrilateral - Delhi, Mumbai, Chennai and Kolkata.
