9 Largest Concrete Structures in the World


Concrete has been used for man made structures starting from the ancient times. Even the great Egyptian pyramids are considered to have been built by employing concrete in their construction [see: http://www.materials.drexel.edu/Pyramids/]. And as time goes by, man has perfected the art of concrete construction making it possible to build mega structures.Utah concrete supplier Altaview Concrete, has put up a list of some of the largest concrete structures in the world, divided into 3 categories: buildings, bridges, and dams.


BUILDINGS

Petronas Twin Towers




Standing at 452 m (1483 ft) and built with 88 floors, the Petronas Twin Towers located in Kuala Lumpur, Malaysia is one of the tallest man made structures ever to grace the face of the Earth. The towers required massive amount of concrete in their 120-meter foundations and are constructed largely of reinforced concrete with facade composed of steel and glass.

CITIC Plaza




The China International Trust and Investment Company (CITIC) Plaza is the tallest concrete building to date. Completed in 1997 CITIC Plaza stands at 391 m (1,283 ft) currently ranks eight in the world's tallest building category.

Burj Khalifa



Originally named Burj Dubai, the Burj Khalifa is currently the world's tallest man-made structure standing at 828 m (2,717 ft). Over 45,000 cubic meters of concrete (110,000 metric tons) were used to construct the concrete and steel foundation. The tower's construction used 330,000 cubic meters of concrete and construction took 22 million man-hours. Also holds the record for highest vertical concrete pumping for any construction at 606 m (1,988 ft).


BRIDGES


Chesapeake Bay Bridge




A dual-span bridge located in the U.S. state of Maryland, the Chesapeake Bay Bridge is one of the longest bridges in the world. It's total length is 6,946 m (22,790 ft). The bridge serves as a vital link between U.S. Routes 50 and 301.


King Fahd Causeway



The King Fahd Causeway is a 17 miles (28 km) causeway connecting Saudi Arabia and Bahrain. The project was estimated to have costed 1.2 billion US Dollars. The 23 m (75 ft) wide mega structure was built using 350,000 square meters of concrete along with 47,000 metric tons of reinforced steel.

Lake Pontchartrain Causeway


The Lake Pontchartrain Causeway is located in Southern Louisiana crossing Lake Pontchartrain. Consisting of two parallel bridges, its longer bridge is often considered the longest bridge in the world depending on definition, stretching up to 23.87 miles (38.42 km). The bridges are supported by 9,500 concrete pilings.

For decades Lake Pontchartrain Causeway was listed by Guinness World Records as the longest bridge over water in the world. In July 2011 the Jiaozhou Bay Bridge in China was named by Guinness as the 'longest bridge over water'.

Jiaozhou Bay Bridge in China
At that time there was some controversy in the USA as the former holder of the record, the Lake Pontchartrain Causeway, disagreed with Guinness and still called itself the longest. It made this claim by ruling on the title according to its own definition that is, how much of a bridge is physically over water, saying that the Jiaozhou Bay Bridge spans water for 25.9 km while Lake Pontchartrain Causeway spans 38.28 km.

In July 2011, Guinness created two categories for bridges over water: continuous and aggregate lengths over water. Lake Pontchartrain Causeway then became the longest bridge over water (continuous) while Jiaozhou Bay Bridge became the longest bridge over water (aggregate)!

DAMS

Grande Dixence




Currently holding the record for the tallest concrete dam in the world, Grande Dixence in Switzerland stands at 285 meters. The construction of the dam lasted from 1953 to 1961 and used 6 million cubic meters of concrete. When the lake is full, Grande Dixence holds 400 million cubic meters of water.


Three Gorges Dam




The Three Gorges Dam is a hydroelectric river dam located in the province of Hubei in China spanning the Yangtze River. Construction started December of 1994 and is said to open in 2011. The dam wall is made of concrete approximated to be 2,309 metres (7,575 ft) long, and 185 metres (607 ft) high. Construction used 27,200,000 cubic meters of concrete and more than 460,000 metric tons of of steel.


Grand Coulee Dam





Grand Coulee Dam located on the Columbia River in the U.S. state of Washington, is currently the largest concrete structure in the United States. It measures 1592 m (5,223 ft) in length and 168 m (550 ft) in height. More than 9 million cubic meters of concrete were used in the construction of this mega dam, enough to make a four-foot wide, four-inch deep sidewalk twice around the equator.

Dear  Dr.   Subramanian,
This structure will also make your list of  major  Concrete Structures:

From:  Latest  ACI  Concrete  SmartBrief :   

Clark Construction, Smoot Construction and H.J. Russell & Co. are managing construction of the $540 million National Museum of African American History and Culture on the National Mall in Washington, D.C. The building, which is 60% below ground and designed to meet LEED Gold certification, features a  210-foot overhang built of ultrahigh-performance concrete..  Construction Dive (6/15)

Dear  Sefi  Engineers,
We are better off  doing big things (Engineering Marvels) .  Let us get back to our (Civil/Structural Engineering)  core  business.  What competition we have to worry about  when we do  structures like this ? One more example of our (Civil/Structural Engineering) contribution to the world.  

From  Latest  ASCE  News  Brief:  27th June 2016:

Videos: $5.25B Panama Canal expansion opens for business.Sunday, a Chinese ship with nearly 9,500 containers was the first vessel to traverse the newly expanded Panama Canal. Ports across the US are in the middle of a series of expansion projects to make room for new, larger vessels.
