Using Basalt Rebar in Construction: A Guide

Basalt rebar is a type of concrete reinforcement that is made from continuous basalt fiber, a product of melting basalt rock without any additives. It offers a number of advantages over steel or fiberglass rebar in terms of strength, weight, durability, and environmental impact.

  • Strength: Basalt rebar has a tensile strength of 1400 MPa, which is 2.5 times higher than steel and 8 times higher than fiberglass. This means that it can withstand higher loads and stresses without breaking or deforming. It also has a similar thermal expansion coefficient as concrete, which prevents cracking due to temperature changes.
  • Weight: Basalt rebar is 5 times lighter than steel and 3 times lighter than fiberglass. This reduces the weight of the concrete structure and transportation costs. It also allows for more flexible and creative designs with smaller diameters and wider spacing.
  • Durability: Basalt rebar is resistant to corrosion, rust, alkali, acid, and salt water. It does not need any special coating or protection like steel or fiberglass. It also does not spall or deteriorate due to moisture penetration from concrete. It has a long service life and does not require maintenance or replacement.
  • Environmental impact: Basalt rebar is an eco-friendly product that does not emit any harmful substances during production or use. It is made from natural volcanic rock that is abundant and renewable. It also reduces the carbon footprint of concrete structures by using less energy and materials compared to steel or fiberglass.

How To Use Basalt Rebar in Construction:

Basalt rebar can be used in various types of concrete structures such as bridges, buildings, roads, tunnels, dams, etc. It can also be used in precast concrete products such as panels, beams, columns, etc. It can be easily cut to length with regular tools and installed using standard techniques.

Some Tips for Using Basalt Rebar Are:

  • Follow the manufacturer’s recommendations for storage, handling, and installation of basalt rebar.
  • Use appropriate connectors and fasteners for joining it with other materials.
  • Avoid bending or twisting it beyond its elastic limit.
  • Provide adequate cover depth for that to prevent exposure to fire or mechanical damage.
  • Use compatible admixtures and additives for concrete mix design with that.
