GFRP Rebar Vs. Steel Rebar

The Best Construction Material.

What Is GFRP Rebar?

GFRP Rebar septic tank construction

GFRP (Glass Fiber Reinforced Polymer) Rebar is a high tensile material used for construction. It is an alternative to steel reinforcement rebar. It is the strongest, cheapest and one of the best building materials for the construction project.

GFRP reinforcing bar has higher tensile strength and corrosion resistance than steel rebar. In addition, GFRP Rebar has been confirmed to be the solution as a significant development in strengthened concrete technology.

What Are The Differences Between Gfrp Rebar Vs Steel Rebar?

  • Stronger:- GFRP Rebar is two times stronger than the steel rebars. For concrete structures, it is required that the structure can handle the construction stress. 
  • Lighter:- The glass fibre reinforced polymer Rebar is ¼ lighter than the steel rebar. The density of the components of GFRP does not exceed 1.9 tons per 1 cubic meter, which is 1/4 less than the density of steel reinforcement bars. The GFRP Rebar is extremely lightweight as compared to Steel rebars.
  • Cost-Effective:- The GFRP Rebar cost is low compared to steel rebar price and provides the best quality for construction. At the same, the cost of steel rebar is high and provides low quality. Cost and quality always matters for the construction business and all the other businesses. 
  • Handle High-Temperature Stress:- The GFRP Rebar is capable enough to handle high-temperature stress. In places like tunnels, Nuclear stations, Power Stations, Highways, etc., where the temperature is always high, we can use this rebar. Steel rebar cannot handle high-temperature stress. Steel rebar melts at low temperatures. 
  • Water-Compatible:- GFRP Rebar is corrosion-resistant to water, so in places like dams, waterside walls, and docks, you can use this rebar. With the use of this rebar, you can reduce construction and maintenance costs. However, steel’s vulnerability to corrosion cost governments and asset owners billions of dollars in maintenance costs to repair or replace aging infrastructure.
  • Easy transportation:- The transportation of the GFRP Rebar is effortless as compared to the steel rebar. You can bend the GFRP Rebar, so it is easy to load this rebar on the vehicle. You can not bend the steel rebar, so the transportation of steel rebar is difficult.

Composition Of GFRP Rebar vs Steel Reinforcement bars

GFRP Rebar, also called (Glass Fiber Reinforcing Polymer) is composed of a polymer plastic matrix with embedded glass fibres. The polymer is made of a vinyl ester, epoxy or polyester thermosetting plastic. The steel rebar is composed of iron with a small percentage of carbon. 

The difference between GFRP Rebar and steel rebar is that GFRP Rebar is more durable, cost-effective, more robust and lighter.

Durability Performance Of Gfrp Rebar Vs Steel Rebar

The durability depends on the outer layer of rebar. Over time, carbon dioxide and chlorides in the air or water enter the pores of the concrete and reduce the alkalinity or pH level of the hardened concrete.

GFRP’s corrosion resistance eliminates carbon and chloride-induced corrosion and protects the construction. As a result, the construction cost and maintenance cost is very low as compared to steel rebar.

Conclusion

GFRP Rebar is better than the steel rebar. GFRP Rebar is a more robust, lighter, and cost-effective material than steel rebar. The construction of GFRP rebar has more benefits than the steel rebar for the construction project.

FAQs

Strength – composite reinforcement has Strength characteristics 2-3 times superior characteristics of steel reinforcement British standard for breaking

Durability – the coefficient of temperature expansion of composite reinforcement is close to the coefficient of thermal expansion of concrete, so that in the concrete structure there are no associated micro-deformations, micro-cracks and the overall durability of the structure is substantially increased.

Chemical resistance  composite reinforcement has great chemical resistance in various aggressive environments, it is not susceptible to corrosion, which also positively affects the durability.

Light weight – fiberglass reinforcement with comparable strength characteristics is lighter than steel reinforcement in times.

Low thermal conductivity  due to low thermal Conductivity “temperature bridges” are not formed in the structure which reduces the thennal Loss to 34% and, accordingly, the conditioning costs of the building.

Easy installation – reinforcing bars can be cut from the bay Of any given Length, fasten with plastic clips, special fasteners-clamps or just a binding wire.
 
 
Easy transportation and storage  you fold the armature into coils, which allows you to use even cars for transportation and save significantly at the same time.

 Due to higher fatigue properties, GFRP rebars have higher resistance to cyclical Loads of high intensity, which makes MRG rebars workable during earthquakes

The change in the ambient temperature on the strength of composite reinforcement is practically unaffected. It can be used at temperatures from -70 to +120 degrees Celsius.
