Since its creation thousands of years ago, concrete has been used throughout the world and by hundreds of different civilizations. As time progressed, the strength and intricacy of concrete structures became an awe-inspiring part of history.
Here are just a few of the more modernized examples of concrete construction around the world.
Building: Burj Khalifa
Standing at a height of 2,722 feet, the 163-story Burj Khalifa became the tallest building in the world when it was completed in 2009. The foundation was built from the combined weight of more than 110,000 tons of concrete and steel, with 192 piles buried more than 164 feet deep. Burj Khalifa’s construction used a total of 431,600 cubic yards of concrete and 39,000 tons of steel rebar. The construction timeline took a staggering 22 million man-hours to complete. With statistics like that, it’s no surprise why the Burji Khalifa easily became the largest skyscraper in the world.
Structure: Three Gorges Dam
The Chinese province of Hubei houses the world’s largest concrete dam. Completed in 2012, the Three Gorges Dam contains over 3,700 cubic yards of concrete, making it one of the heaviest concrete structures in the world. With construction starting in 1994, the dam was designed for power and flood control. It’s responsible for an annual power-generation capacity of 84.7 TWh, which reduces coal consumption by 31 million tons per year and helps to prevent 100 million tons of greenhouse gas emissions.
Bridge: Beipan River Bridge
This bridge on the Guanxing Highway near Xingbei Town was built with a concrete cable-stayed connection and carries four lanes of traffic. Sitting at a height of 1,200 feet and spanning a length of over 1,200 feet long, it is the world’s highest bridge. This world record-holding concrete
structure reduces travel times between popular Chinese cities from four hours to a little over an hour.
Concrete can be used in amazing ways for a myriad of projects, ranging from small DIY construction to significant structures that will last thousands of years into the future. For a quote on your next construction project, contact G-CAT Construction today.
