BRINGING ROADS TO LIFE

Introduction

All living things heal themselves but ever imagined artificial things coming to life and healing themselves. As scary it might sound but when man-made constructions start healing themselves, they are more long-lasting than regular constructions. One such project is brought to reality by Nemkumar Banthia, a professor in the department of civil engineering at the University of British Columbia (UBC) and CEO of IC-IMPACTS. 
The self-healing road project was brought to life in the town of Thondebhavi, outside Bangalore, connecting the small town to the rest of the country with a road design of 650m that resists heavy rains, intense heat, and poor drainage. 

Construction 

Self-healing roads are ultra-high-strength concrete reinforced with hydrophilic polyolefin fibers with advanced nano-coatings that are more resistant to cracking. They make use of locally sourced fly ash, a heterogeneous by-product material produced in the combustion process of coal used in power stations. Every time you have a crack, you always have anhydrous cement to which water gives its hydration capability, producing further silicates that close the crack in time. This loop continues healing the roads and giving them an elongated life span of over 15 years.

Benefits

The self-healing roads reduce the required cement component by 60 percent. The cement industry currently contributes around five to seven percent of global emissions. Thus these roads can reduce pollution and global warming due to concrete pollution. The road’s thickness, at about 100 mm, is about 60% less than that of a typical Indian road, reducing the cost and materials required by about 30%. These roads have a life span of about three times our normal Indian road. It can play a major role in the economic development of the country as with transportation development per capita income would prosper, thus making the economy stronger. 

Conclusion

Transport infrastructure influences both economic growth and social cohesion. A region cannot be competitive without an efficient transport system. Thus the project of self-healing roads is revolutionary in itself and is aimed to become beneficial for many states in India as well as Canada as IC-Impacts works towards the cause. 

It’s the year 2020 and while self-driving cars are not available to the public yet, roads can now heal themselves and are a reality for the common masses, thanks to the innovation of an Indian UBC engineering professor.

CYCLONE RESISTANT BUILDING CONSTRUCTION Cyclones have been an inescapable situation in India, especially in the eastern states of Odisha, West Bengal, and Andhra Pradesh. This calls for the construction of cyclone-resistant buildings in cyclone-prone areas to avoid loss of life and property. Low-lying coast areas, river floodplains, and sea-shore areas are highly vulnerable to cyclones. Certain settlement pattern even causes "funnel effect" which results in greater damage. While it's a common belief that heavier buildings are safer, in reality, a well built and engineered house provides better safety. Minimum standards for the design, construction, and performance of buildings to withstand extreme climate-related natural hazard events depending upon their locations should be set. We know cyclones are beyond human control but measures can be taken to reduce the loss of lives like evacuating people to safe areas, quick recovery of important fa...

Central Vista Project: Transforming the Political Face of India, the Civil Way

Image
    Source: Wikipedia     Central Vista Redevelopment Project  refers to the ongoing  redevelopment  to revamp the Central Vista, India's central administrative area located near  Raisina  Hill, New Delhi . The area houses India's government and parliamentary offices and has  been  described as the "power corridor" of the country. The project seeks to improve infrastructure for the Government of India, including retrofitting and refurbishing some heritage buildings to make them functional and safe.        Source: The Hindu   The Central Vista Redevelopment Project was launched in 2019 .   The project includes converting North and South Blocks into public museums while creating an ensemble of new secretariat buildings to house all ministries, relocating the Vice President and the Prime Minister's offices  and residences near the North and South Blocks, and revamping the 3 km (1.9 mi) long  Rajpath  between  Rashtrapati...

Demolition of Building Structures

Image
Demolition of a building is the process of dismantling or destroying a structure after its life of serviceability by pre-planned and controlled methods. It is the science and engineering in safely and efficiently tearing down buildings and other artificial structures . The tallest planned demolition of a building was the 47-storey Singer Building in New York City , built-in 1908 and torn down in 1967–1968 to be replaced by One Liberty Plaza Building Demolition methods: There are two types of demolition methods used for buildings and structures, Non-explosive demolition and Explosive demolition. In the non-explosive method, demolition of a structure is done with some equipment, without the use of any explosive. In contrast, in the explosive method, demolition is done with the help of bombs and explosives. Building Demolition Process: Different steps are involved in the process of demolition of building structures. They are: 1. Surveying 2. Removal of hazardous materials 3...
