Fibre-reinforced concrete generally has more tensile strength than normal cement concrete, and it can be used in tough situations where there’s a lot of support needed. It displays a very high ductility strength and can prevent cracks from appearing. 

Fibre is a small piece of either flat or circular reinforcing material. Although you get different types, there are a couple of characteristics that stay the same. 

Each fibre adds something different to the concrete like steel fibres, glass, synthetic, and natural fibres. There are a lot of other advantages of carbon fibre we can look at

Carbon fibre will add strength, durability, and resistance to tension – which will allow you to make your design more flexible and creative. You can also add strength to existing structures. 

For example, FRP Application or Fibre-reinforced plastic (FRP) is made of the polymer matrix. FRPs are used to add to existing structures to improve their load-bearing capacity and to maintain the structure as a whole. This is only one of the many applications of carbon reinforced fibre.

Carbon Fibres

Carbon fibre reinforced concrete can work under pressure, but it’s also very light in weight;  its composite materials consist of fine grain and super-high-strength concrete, as well as other carbon fibres. 

You’d think that steel fibre has a higher strength, but carbon fibre has a higher resistance capability than steel fibres at only 25% of the weight. 

Carbon fibres solve the problem that concrete is weak when it comes to flexibility, since the flexural strength of concrete doubles when carbon fibre is added.

Advantages of Fibre When Compared to Steel:

Carbon fibre is more advantageous than steel in some areas. Here are the reasons why:

  • It’s almost 80% lighter than steel
  • It’s durable, and it won’t corrode easily
  • It’s tensile strength is multiplied by 5
  • It’s stiffness is multiplied by two
  • It can tolerate high temperatures

Uses in Civil Engineering

Carbon fibre reinforced concrete is being researched at an academic and post-graduate level since it seems very promising for a lot of engineers. 

It’s cheap and sustainable, making it great for strengthening any concrete structure. As it can also strengthen existing structures, it’s more cost-effective than demolishing the whole structure. 

The load-carrying capacity of bridges and other structures can be increased by using carbon fibres.

Carbon fibre also has a high resistance to heat. That’s why Thomas Edison was the first to use carbon fibres for filaments for his experiments on light bulbs. 

Other applications include, but are not limited to:

  • Carbocrete balconies
  • Shore protection barricades
  • Carbocrete bicycle stands
  • Artistic structures that you can use for shadow spots (it can be artistic since it fares well when put under tension)
  • Office buildings


As you can see carbon fibre reinforced concrete has many uses. With carbon-reinforced fibres, it makes sense that the construction industry has seen significant improvements globally. This is because carbon-reinforced fibres have a high-performance rate in corrosion resistance, high strength situations.
