Importance of concrete construction

Concrete buildings play an extremely important role in modern society. They are the main shaper of our urban appearance and the witness of economic development and social progress. Whether it is a towering skyscraper or a warm and comfortable residential area, whether it is a solemn public facility or a unique artistic building, concrete plays an indispensable role in it.

Concrete admixtures are equally important in the construction of concrete buildings. Although these chemicals or mixtures only account for a small proportion of the total volume of concrete, they have a significant impact on the performance and characteristics of concrete.

The Middle East has more than 20 of the world's tallest buildings, including 12 in Dubai alone, one of which is the tallest.

At 828 meters tall, the Burj Khalifa is taller than the Empire State Building and Willis Tower, making it the tallest building on earth.

 

Opened in 2010, this mixed-use megastructure is the centerpiece of a new mixed-use development in downtown Dubai.

This is also very symbolic. The Dubai government hopes to expand its economic scale. The key to making Dubai an entertainment center in the Middle East is to obtain the title "the tallest building in the world."

 

Scientific research on tall buildings has progressed slowly for decades, but the completion of the Burj Khalifa represents a giant leap forward in this field.

Philip Oldfield, School of Built Environment, University of New South Wales:

"The uniqueness of the Burj Khalifa lies in its shape and appearance. It is designed and optimized to resist wind and shock absorption. The floors on different floors are built into non-parallel structures. This design can ensure that when strong winds strike, The vortex generated at the back of the building will spread to different floors, and the time and floor of the action are not fixed, preventing the building from shaking back and forth."

The Y-shaped tower forms three wings, adding to the building's stability.

The construction team faced huge challenges when building in the sand and heat of Dubai's desert.

Virginia Tech architect Stephen Eyre:

"Because there is no bedrock in the desert, the engineering team must rely on friction to build the foundation, driving very deep piles in the sand. Another question is how to prevent the concrete from quickly Pumping to the top of the building while it solidifies?"

 

In this case, engineers invented a mixture containing ice flakes to keep the cement cool enough.

Dubai has become a popular tourist destination today due to the Burj Khalifa.

Dubai is now considered the most popular tourist destination in the world. Its shopping malls are high-end and luxurious, its luxury hotels and resorts are extremely prestigious, its beaches are pure and pollution-free, its nights are vibrant, and its architecture is magnificent. The entire country is world-famous.

Jason Barr, professor of economics at Rutgers University-Newark:

"Thousands of tourists come to Dubai and go to observation decks. Across the world, whether in Dubai, Chinese Taipei, or Shanghai, observation decks are a powerful motivation for building super high-rise buildings because they are a 'money-making tool'. '"

More than a decade after its construction, the Burj Khalifa remains the tallest building in the world, but how long can this record remain?

Jeddah, Saudi Arabia, plans to build the world's first 1,000-meter-tall building, the Jeddah Tower, which has already completed 38 floors. Saudi Prince Alwaleed hopes to replicate the Dubai model in his own country.

 

Jeddah, Saudi Arabia, was supposed to be a futuristic metropolis, home to a new "world's tallest building" and attracting tourists.

Construction work on the Jeddah Tower began in 2013, but the project has stalled.

Virginia Tech architect Stephen Eyre:

"When the foundation was laid and only one-third of the building structure was built, there was a regime change in Saudi Arabia, and construction has been suspended since then. Only about one-third of the project is left, but the start time Is still unknown."

 

There still needs to be sign of work resuming on the Jeddah Tower. What will be the future fate of this skyscraper?

Jason Barr, professor of economics at Rutgers University-Newark:

"Today, the majority of the world's population lives in cities. This number continues to rise. As more people settle in cities and economies develop, buildings will accommodate more people on the same land area. People. Fundamentally, skyscrapers are a response to urbanization."

Philip Oldfield, School of Built Environment, University of New South Wales:

"Theoretically, using traditional techniques and high-performance steel and concrete as building materials, we can build a 2,500-meter-high skyscraper. But the key question is, should we do this?"

The carbon dioxide released during the construction, use and demolition of buildings accounts for 37% of total human carbon emissions. This is a huge number.

For example, using concrete accounts for 8% of total CO2 emissions. Therefore, we should consider how to build skyscrapers more sustainably.

Virginia Tech architect Stephen Eyre:

"In our lifetime, we will have to wait and see whether humans will build a skyscraper taller than the Burj Khalifa. This is what all humans have been doing. A long time ago, humans piled stones one by one to build Stonehenge, then the early pyramids, then the Eiffel Tower, and now the Burj Khalifa. I believe we will continue to strive towards the heights of heaven."
