Why is fiberglass rebar a good choice for reinforcement?
Fiberglass rebar is an excellent choice for reinforcement because it is strong, durable and does not corrode. It is also light weight and easy to handle, making it ideal for a variety of applications.
Glass fiber reinforced polymer (GFRP) rebar has turned out to be a perfect alternative to traditional reinforcement materials such as black rebar and epoxy coated rebar. Traditional reinforcement techniques have failed to develop a corrosion-free mechanism that can keep concrete structures in good shape.
The tensile strength of FRP rebar is usually 1.5 to 2 times higher than that of steel, so it can well balance the high compressive strength of concrete. It also provides excellent fatigue resistance, making it suitable for cyclic loading situations such as those found on roads and bridges. In addition, the weight of the composite rebar is one-fourth of the steel of the same performance. There are many practical benefits here. There is less wear and tear on construction workers who have to carry and install it, and less need for cranes and other heavy lifting equipment. It is easy to cut with normal cutting tools and will not damage the blade. More rebar can be transported per truck without exceeding legal loading limits. For bridges and similar structures, a higher strength-to-weight ratio provides greater load-bearing capacity for a given structure, or a possible opportunity to reduce the size and weight of the overall structure. Composite rebar can also be used in weight-sensitive applications with poor soil bearing properties, in seismically active areas, or in environmentally sensitive areas where moving heavy equipment is not desirable.
