Carbon concrete is an endurable construction material made from concrete and carbon fibers or bars. The Carbon is mixed into the concrete via mesh-like textile mats between its coatings or as randomly or uniformly distributed fibers throughout the concrete. Carbon fiber enhances the tensile strength of concrete to a terrific extent.

Carbon bars can also support fine-grain concrete to create high-strength carbon-reinforced concrete. Since it is more strong and more delicate than standard concrete, it can create aesthetically attractive structures. It suits sustainable, resource-saving, less material-intensive, and more lightweight construction.

  1. Methods to Produce Carbon Concrete  

a. Carbon fiber can be randomly distributed throughout the concrete to make carbon concrete.

b. Mesh-like textile mats made from carbon fibers can be positioned between coatings of fine concrete.

c. Carbon fibers can also be spread throughout concrete with a nozzle process in a targeted way. In this manner, the tensile strength of concrete is enhanced.

d. Carbon bars reinforce fine concrete to create high-performance carbon-reinforced concrete.

  2. Advantages of Carbon Concrete  

a. It does not rust, a huge problem in reinforced concrete cases. So, a thick concrete cover is not needed for corrosion protection.

b. It improves concrete strength five to six times compared to reinforced steel.

c. Carbon fibers can be made from any substance that includes carbon.

d. The life span of Carbon is hugely longer than reinforced steel. In Germany, the life service of bridges constructed from reinforced steel is about 40-50 years.

However, the life span of the Albstadt bridge, made from textile-reinforced concrete, is about 80 years without much maintenance and rehabilitation.

e. It is four times lighter than traditional concrete, permitting delicate and aesthetically pleasing designs like the building.

f. It releases half of the embodied Carbon emitted by conventional concrete. This is because carbon concrete reduces the consumption of construction materials.

  3. Disadvantages  

The most crucial issue for carbon concrete is its high production cost of about 20 EUR/kg compared to 1 EUR/kg for reinforced concrete production.

Regardless, this does not show the truth because carbon concrete decreases the material involvement by up to 75%, decreasing the project’s cost.

Carbon’s strength, longevity, and corrosion opposition offset the additional cost used on production.
