Reinforcing concrete structures with Basalt rebars

Traditional reinforced concrete  structures often encounter durability problems due to cracks caused by corrosion expansion of steel bar. With respect to steel bar, Basalt Fibre Reinforced Polymer (BFRP) bars present superior corrosion resistance as a kind of novel nonmetallic reinforced bars with high chemical stability. Recently non–ferrous reinforcement, BFRP bars are regarded as a potential alternative material to replace traditional steel bar in reinforced concrete structures subjected to extreme corrosive environment, such as ocean concrete structures .

The bond-slip behavior, which affects bar anchoring, lap splice strength, concrete-cover requirement, serviceability, and ultimate states, is a key feature for the successful application of basalt fibre reinforcement bars as internal reinforcement in concrete structures . It should be noted that the bond-slip behavior of BFRP bars in concrete was different from that of steel bar . Although some achievements about the bond-slip behavior between BFRP bars and concrete have been made, most of them were focused on small size basalt bars (<Ф 10 mm). However, the bond-slip behavior between large size BFRP bars and concrete is different due to larger interfacial transition zone, internal bleeding, and smaller specific perimeter. In addition, long term bond-slip behavior of BFRP bars in concrete exposed to marine environment has not been clarified yet.

Basalt Rebar is available in 4-40mm diameters up to 5.5m length
