Fiberglass Reinforced Polymer Rebar: A Stronger, Lighter and More Durable Concrete Reinforcement
Fiberglass reinforced polymer (FRP) rebar is a composite material made of a polymer matrix reinforced with glass fibers. It is a more durable, proven and successful reinforcing alternative to steel rebar in concrete applications. FRP rebar has many advantages over steel rebar, such as:
Higher tensile strength: FRP rebar can withstand up to 2 times the tensile stress of steel rebar of the same diameter.
Lighter weight: FRP rebar is up to 7 times lighter than steel rebar in concrete flatwork applications and 4 times lighter than steel rebar of the same diameter. This reduces the transportation, handling and labor costs and improves the productivity and safety of the construction site.
Corrosion resistance: FRP rebar will never rust, unlike steel rebar, which can corrode and deteriorate over time due to exposure to moisture, chemicals, salt, etc. This enables more durable and longer-lasting concrete structures that require less maintenance and repair.
Non-conductivity: FRP rebar is electrically and thermally non-conductive, which eliminates the risk of electrocution or fire hazards in electrical or magnetic environments. It also reduces the thermal expansion and contraction of concrete, which can cause cracking and spalling.
Applications of FRP Rebar
FRP rebar can be used in various residential, commercial and structural concrete applications that require reinforcement for shrinkage crack mitigation or load-bearing capacity. Some examples of applications are:
· Parking lots
· Sidewalks
· Patios
· Pool decks
· Driveways
· Bridge decks
· Barriers
· Seawalls
· Balconies
· And more
Performance and Parameters of FRP Rebar
The following table shows the typical properties of fiberglass rebar according to ASTM D7957 standards. The actual values may vary depending on the manufacturer and the product.
| Bar Size | Nominal Diameter (mm) | Cross Sectional Area (mm²) | Ultimate Tensile Strength (MPa) | Ultimate Tensile Load (kN) | Modulus of Elasticity (GPa) |
| #2 | 6.4 | 32.2 | 1034 | 33.3 | 46.9 |
| #3 | 9.5 | 71.3 | 1034 | 73.7 | 46.9 |
| #4 | 12.7 | 127.6 | 1034 | 131.9 | 46.9 |
| #5 | 15.9 | 199.6 | 1034 | 206.3 | 46.9 |
| #6 | 19.1 | 287.0 | 1034 | 296.8 | 46.9 |
| #7 | 22.2 | 387.1 | 1034 | 400.0 | 46.9 |
| #8 | 25.4 | 508.0 | 1034 | 525.3 | 46.9 |
How to Use FRP Rebar
FRP rebar can be installed in a similar way as steel rebar, with some modifications to account for the different properties of the material. Some general guidelines are:
Use appropriate tools to cut, bend and tie FRP rebar, such as diamond blades, mandrels and plastic ties.
Follow the design specifications for spacing, cover depth, lap length, etc., as recommended by the engineer or code.
Avoid damaging the surface or core of FRP rebar during handling, storage or installation.
Protect FRP rebar from direct sunlight or high temperatures during storage or installation.
