When it comes to reinforcing construction projects, the choice of rebar plays a pivotal role in ensuring structural integrity and longevity. Two main contenders in the rebar arena are the traditional steel rebar and the composite (non-metal) rebar, each presenting a unique set of advantages and drawbacks. Basalt Fiber Rebars BFR are very useful for concrete because they add strength and durability and reduce shrinkage, and they are also non-rusting and do not corrode over time.
Steel Rebar: A Time-Tested Classic
Fact: Undoubtedly, steel rebar stands as the time-tested classic and remains the most commonly used reinforcement in construction projects. Steel rebar has been an integral part of civil and industrial construction for years.
Composite Rebar: Embracing the Future
Fact: In recent years, composite rebar has gained traction, presented an array of unique benefits when compared to traditional steel rebar. The most prevalent types of composite rebar in the construction industry are basalt composite rebar and fiberglass composite rebar.
Basalt Rebar: The Epitome of Durability
Fact: Manufactured using a specialized process, basalt rebar is created from thousands of basalt fibers infused with an epoxy resin-based composition, which polymerizes as it passes through the production line. The result is an exceptionally robust reinforcement, boasting 2.5 times the tensile strength of steel rebar and 1.5 times that of fiberglass rebar. It finds its true potential in locations where extreme strength is required, such as in industrial floors, foundations, road surfaces, and coastal reinforcements.
However, it’s important to note that basalt rebar’s lower elastic modulus makes it less suitable for ceilings exceeding 3 meters in length. Despite this limitation, its impeccable performance in areas prone to aggressive media and temperature fluctuations makes it an excellent choice for various applications.
Fiberglass Rebar: A Glass-Based Alternative
Fact: Following a similar manufacturing principle as Basalt fiber rebar, fiberglass rebar is crafted from glass roving infused with a polymeric binder. While it shares similarities with its basalt counterpart, fiberglass rebar falls short in technical parameters due to the inherent characteristics of glass as an artificial material.
Features of Basalt Composite Rebar
One of the most striking characteristics of basalt composite rebar is its ability to maintain material integrity under any load. This exceptional quality allows it to exhibit a comprehensive range of tensile strength characteristics.
In terms of strength, basalt reinforcement surpasses the resistance of steel. Moreover, when subjected to tension, basalt reinforcement experiences only 8-10 times less relative elongation compared to its steel counterpart of corresponding strength, ensuring minimal deformation and excellent dimensional stability.
The advantages of composite reinforcement are not limited to its mechanical properties alone. Remarkably, the specific gravity of composite reinforcement is merely one-fourth that of steel, translating into reduced framework weight, handling costs, and transportation expenses.
An additional significant benefit is that basalt reinforcement is non-corrosive, extending the concrete’s service life significantly.
Furthermore, the coefficient of thermal expansion (CTE) of basalt rebar closely aligns with that of concrete, eliminating concerns of cracks or exposed reinforcement mesh due to temperature variations during the structure’s operation.
The thermal conductivity of composite rebar is another winning feature; it is over a hundred times lower than that of steel, leading to improved thermal performance in reinforced concrete.
Adapting to diverse environmental conditions, basalt fiber rebar retains its working properties even in low-temperature scenarios.
The versatility of basalt rebar extends further to being radio-transparent, diamagnetic, and dielectric, making it suitable for applications requiring specific electromagnetic properties.
With its array of exceptional properties and adaptability, basalt composite rebar has proven to be a game-changer in the construction industry. By embracing this innovative material, construction projects can enjoy enhanced durability, reduced maintenance, and improved overall performance in diverse settings. As the construction industry continues to push the boundaries of possibility, the adoption of composite materials signals a promising path towards a more resilient and sustainable future.
