Concrete Mixers: How Cement Has Shaped The World’s Most Spectacular Bridges



The world as we know it today has been drastically shaped by concrete mixers and concrete, and it’s no exaggeration to say that cement has been one of the most impressive inventions. Throughout history, humans have used cement to create ancient wonders, including some of the world’s most spectacular bridges.


Today, as we continually expand our cities and make improvements in transportation systems, cement mixers play a vital role in building the modern brides we use every day. This article covers the history of cement bridges and how they shaped the industry in the world we know today. Also, we’re going to take a closer look at concrete mixers and their integral role in building modern bridges around the world. We use bridges all over the world, but it is concrete mixers which have a big role in shaping them.




Cement And The History Of Architecture


The use of cement in architectural projects dates back to the roman empire and the building of the Egyptian pyramids. When the cement was invented, humans were able to build incredible structures that were strong enough to withstand even the harshest elements. Today we can still view the ruins of Roman structures such as the Pantheon and aqueducts, and many of the bridges that were built hundreds of years ago are still in use today.


Without cement, the modern and civilised world we know today might not exist. Building cement bridges, and infrastructure has made it possible for humans to advance their urban settlement, create transportation routes and create buildings that can withstand the elements. Today, cement technology has advanced drastically, and the use of cement mixers in building and construction allows us to reach new possibilities in architecture and design.


The Role Of Concrete Mixers In The Construction Of Bridges


Construction and cement go hand in hand, and this often unnoticed material is something we come into contact with daily. Cement is the binder in concrete, acting as a glue and hardening agent to strengthen the concrete during construction. Today cement mixers are used to mix the cement, concrete aggregate and water for the perfect mixture to use on any construction site when building modern bridges across the globe.


Concrete has proven to be one of the most versatile materials when it comes to constructing elaborate architectural structures.


Concrete and cement have been used to build more bridges across the world than any other material. This is due to its extreme strength and durability. Concrete is easy to build with, and architects can simplify the construction process when building concrete bridges. It is by far the best material to use in bridge construction, and even steel or cable bridges will still make use of a good deal of concrete in their foundations, even if it is not completely visible. The most difficult and demanding bridge construction projects would not have been possible without cement mixers and the development of concrete.


The following are a few of the top reasons why concrete has been consistently used for the construction of bridges since its invention:


It is strong and durable: Concrete is an extremely long-lasting material, and it can withstand some of the harshest conditions. Even when exposed to extreme environmental circumstances, it needs very little maintenance. Concrete bridges can stay in working condition for hundreds of years, and there are many historical bridges still being used today.


It is functional and aesthetic: Cement and concrete can be shaped into any form and design, making the options endless when constructing with this material. Cement mixers and concrete allow architects to bring their most imaginative projects to life. It is functional, but also aesthetically pleasing with the right design, and many architects opt for concrete finishes to enhance the aesthetics of their projects.


It is a versatile material: Due to its versatility, concrete can be used to create a range of structures, and bridges can be constructed in a range of forms. Some bridges are made entirely out of concrete, whilst others can combine concrete with other materials such as steel, depending on the architects’ preference. Bridges made out of concrete can incorporate arches, pillars, beam bridges and so much more.


It is easy to use and cost-effective: Building with concrete is easier than building with other materials, and it often speeds up the construction process. Making building easier and faster can save a lot of money, and certain projects are only possible due to having the option of concrete available. Concrete is by far the most cost-effective way to build strong and effective bridge structures.


It is an environmentally friendly material: Concrete is one of the most sustainable materials used in construction projects today as it is made from raw materials. It also lasts a very long time, making it a sustainable choice for bridge construction. Concrete is a recyclable material, and it shouldn’t leave any negative impacts on the environment even after the bridge is in use.




Types Of Concrete Bridges:


Arch Bridges: These are one of the oldest and most traditional concrete bridges. Today the arches are still used but the design has become more modernised./ The arches allow these bridges to extend over large distances.


Beam Bridges: These bridges are fast and easy to build. They are most often built over existing roads or railways.


Slab Bridges: These are made up of individual concrete slabs and decks. They are primarily used for bridges needed to cover short distances.


Stressed Ribbon Bridges: These bridges are designed as pedestrian bridges and are usually much smaller. It is a type of suspension bridge that uses cables and a concrete deck.


How Bridges Have Impacted The World


Since ancient times, bridges have been a fundamental part of growth and development. They have changed the world, and can often have more benefits than just transportation. Bridges connect people and can benefit entire communities and cities when built in the correct area. The following are just a few positive impacts bridges have on modern society.


Bridges can improve a city’s economy: Bridges allow people to have access to new jobs and businesses, as residents can easily commute to new areas. They also play a major role in shipping goods and raw materials between factories and suppliers and can ensure a city is economically successful.


Bridges can connect two communities: Connecting communities by bridge allows people to support one another, both economically and socially. Different areas may have different assets, and a bridge can allow both communities to benefit.


Building a bridge can benefit many businesses: When building a large construction project like a bridge, a large labour force is needed. Wages earned by the project can benefit an area greatly, and many businesses can benefit.


5 Famous Concrete Bridges From Around The World


Certain bridges have become impressive tourist attractions around the world, and they can function as important landmarks for a city or town. Many of these bridges are made of reinforced concrete and have relied on mixers and impressive architecture to be successfully completed. The following are just a few examples of famous concrete bridges from around the world.


Golden Gate Bridge, USA


The golden gate bridge is an iconic image which appears on many postcards, and it has become a large tourist attraction. It was built in 1937 to connect San Francisco to the Pacific Ocean. The construction of this bridge was extremely difficult, and it is seen as an incredible engineering feat. It is a large suspension bridge made out of steel and cables. Concrete has been used to anchor the bridge on each end, connecting the two land masses.




Tower Bridge, UK


Tower Bridge is a very famous old bridge situated in England. It was built in 1886, and the project took about 8 years to complete. Over 70,000 tons of concrete were used in the construction of this bridge. The concrete makes up the two large piers which support the steel structure of this bridge.


Shibanpo Yangtze Bridge, China


This impressive bridge is one of the longest bridges in the world. It has made use of modern concrete and cement mixers to complete the project.

It has three large arches, with the tallest arch being 63 metres high. It has been built using the highest concrete technology to ensure there are no weak points, and it is designed to last 120 years.


Concrete Mixers For Construction


When constructing large-scale projects such as the bridges mentioned above, it is necessary to have all the correct technology and tools to complete a project. Cement mixers are used to prepare large quantities of concrete for projects such as the Sheikh Zayed Bridge.


These large-scale concrete mixers are made of a rotating drum which ensures consistent mixing for high-quality concrete in large quantities. Some trucks are built to include cement mixers, which make it easy to transport the concrete around the site without compromising the quality. Construction is made quick and efficient due to these industrial machines. The following are a few benefits of using cement mixers on large-scale projects:


  • The project can be completed faster and more efficiently.
  • Cement and concrete can be made on site, this can eliminate transport costs.
  • They can prevent injuries and improve the health and safety of the site.
