Definition Basalt Rebar

From Wikipedia, the free encyclopedia

Rebar (short for reinforcing bar), also known as reinforcing steel, reinforcement steel,[1] is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Rebar's surface is often patterned to form a better bond with the concrete.

The above description from the Wikippedia does not include Basalt, but nowadays, Basalt is available, as well.

Below are a few highlights utilizing Basalt instead of e.g. the commonly used Steel:


  • Higher specific strength
  • Approx. 10% of Basalt Rebar needed to achieve the same results as with Steel Rebars
  • Resistant to corrosion or deterioration caused by natural elements
  • Alkaline and acide resistant
  • Same thermal expansion as concrete, reducing the formation of cracks

Suitable Applications: 

  • Concrete
  • Highway
  • Construction
