Basalt bar is a high-strength and durable basalt fibre bar with a diameter from 8mm This reinforcement is produced in straight bars with a length of 2.5m. Basalt BAR has the advantage over steel reinforcement in faster installation and less connection. This surface treatment consists of applying a silica sand before the pultrusion process. This process gives the bar an improved bond to concrete by up to 60%
The use of Basalt BAR composite reinforcement increases the lifetime of concrete structures as it is unaffected by the presence of chlorides and carbonation. In fact, research suggests the carbonation process will improve the strength of the concrete in the long term. Basalt BAR has a high resistance to corrosion in acidic, alkaline and other corrosive environments.
High tensile strength (1200 MPa)
Low density (2.0g / cm3)
Low thermal conductivity (0.46W / m2)
Absolute environmental and fire safety
Basalt BAR composite reinforcement has undergone physical and mechanical tests at various universities around the world and is certified against ASTM D7957 – currently the only standard for the use of FRP in reinforced concrete.
