BFRP Rebar
Made of highstrength basalt fiber and vinyl epoxy resin which have been pultrued, winded,surface painted, BFRP rebar is a construction material that features high strength and excellentcorrosion resistance. It can also be composite molded and manufacturedcontinuously. Compared with traditionalreinforced concrete structure, BFRP rebar has superior mechanical properties, physical properties, chemical properties and it will extend the life ofthe reinforced concrete structure in obviously corrosive conditions.
Features
1. The tensile strength of BFRP rebar is two times more than ordinary steel ofthe same size.
2. It has excellent corrosion resistance which can’t be realized by any otherfiber fabric.
3. The density of BFRP rebar is just about 1/4 of ordinary steel.
4. It has excellent wave transparence and no shielding.
5. With its similar thermal expansion coefficient, the BFRP rebar won’t producehigh temperature stress.
6. No electric conductivity nor thermal conductivity.
7. BFRP rebar can be prefabricated to standard curve and other shapes.
Application
1. BFRP rebar can be used tosolve the problem of corrosion resistance and lifetime of bridges as well asreinforced concrete structures in acidic and alkaline areas such as north areaand wet south area.
2. It can be used to solve the difficult technical problem of the continuousreinforced concrete roads in highways and the welding of the reinforcedconcrete.
3. By mitigating the weight of the bridge, it can enhance the bearing capacityas well as the life span.
4. BFRP rebar can be used to permanently anchor the mine, tunnel and roadslope.
5. Simplified construction difficulty results in the improving of efficiency,reducing the construction period and saving the cost of the production.
6. BFRP rebar can reduce construction cost and the total project expenseas well as maintenance costs.
