Fiberglass Rebar – Building A Sustainable Future

Fiberglass Rebar - Building A Sustainable Future

Being at the pinnacle of human evolution, the way we construct and build structures proves that our existence has gained a new level of livelihood and we are still moving forward. This modernization of our development requires innovation as well. Innovation that will assure the safety, sustainability and the survival of our future generations. One particular feature of this evolution is the construction materials used in the infrastructure of the cities we live in. Perhaps, the most influential material of construction today is Glass Fiber Reinforced Polymer (GFRP).

Most developed countries around the world are now relying on sustainable construction methods to save resources and provide buildings with a long service life. The use of traditional materials is decreasing and the use of new materials that can be recycled, reused and reduced consumption are being increasingly introduced. The use of GFRP instead of traditional steel is being used evidently. Especially in large structures, bridges, and buildings which are intended to last for a very long time.

Features of GFRP Rebar:

GFRP Resists Corrosion

The reason why GFRP is being used more when it comes to sustainable construction is that it has corrosion free attributes. Steel on the other hand, no matter how strong it is or versatile it is, can easily corrode and lose basic strength-based properties that were necessary for building structures. In this aspect, the use of GFRP carries much more benefits than strength alone.

Being a polymer, GFRP is able to withstand the extreme weather conditions and continuous rain and water submerged conditions. The main causes of corrosion are the oxidation and chloride ion-based chemical attacks. GFRP has been made to withstand such corrosive agents allowing the structure to survive for very long periods of time.

As per the recent tests of GFRP based structures, there has been no loss of strength whereas steel and similar materials lose their strength-based attributes after a few decades.

GFRP Is Economic

Part of the cost of construction materials consists of transportation, weight and storage. Being lightweight and having fewer chances of corrosion, the storage and transportation cost of GFRP is much less than steel.

Some of the most useful aspects of GFRP are that its life expectancy and strength are greater than steel in all dimensions. Being a quarter of the weight of steel, the use of this material has been providing the construction industry the needed competitive edge in the market.

GFRP Is an Insulator

Steel is actually a conductor of heat and electricity; this can sometimes be a problem, depending on its application. A good example would be hospital rooms with x-ray equipment. These rooms usually require GFRP reinforcement, as steel would cause issues.

Similarly, in extreme weather, heat and cold are conducted by steel. GFRP in this sense again becomes a useful alternative as it cannot conduct electricity or heat and cold. This provides extra assurance as to why fiberglass rebar is an excellent alternative to steel rebar.

GFRP For The Future

The construction materials for the future need to be more cost-effective and should have qualities that easily surpass traditional raw materials used in construction. The economic activity that is generated by construction is actually a collaboration of various other industries, therefore, it is important that innovation and modernization are practiced in all industries.

The global warming issue is getting worse. Weather conditions are becoming more extreme, natural calamities like floods, tsunamis and tornadoes are becoming more ferocious every year. The cost of rehabilitation after natural disasters is worth trillions of dollars globally and billions of dollars in the US and Canada alone.

Sustainable Construction

The construction industry is also facing much-needed changes mainly due to the competition and the increasing cost of materials worldwide. In this sense, it will be a good approach to use materials that appreciate sustainable construction philosophy. The three Rs of construction Reduce, Recycle and Reuse are also part of the modern construction practices that save resources and minimizes the cost of construction.

Today, there is enough evidence that supports GFRP as being among one of the best construction materials that provides maximum utility to all the stakeholders in the construction industry.

When it comes to infrastructure, it’s important to plan strategically as well as for the future. This requires project managers to select the best construction materials for their needs. The main advantages of GFRP is that there are no risk factors involved when it comes to corrosion, strength and being economically friendly.

GFRP: An Emerging Material For Civil Infrastructure

GFRP: An Emerging Material For Civil Infrastructure

Glass fiber reinforced polymer (GFRP) and other variants of composite materials are reshaping the dynamics of the construction industry worldwide. GFRP materials like fiberglass rebar are gaining increasing attention due to their superior corrosion resistance, excellent weight ratio and higher durability. This is why advanced composites are said to be the material of the future.

The application of fiberglass rebar for concrete reinforcement has been a hot topic in the civil engineering community for over two decades. Truly unique and flexible features of GFRP are opening new possibilities for the international construction industry to resolve longstanding structural issues such as corrosion and the need for heavy maintenance.

The use of metals in construction and other industries comes with corrosion and deterioration. Concrete structures reinforced with steel or other traditional materials eventually succumb to corrosion and make it financially difficult for structure owners to repair and maintain damaged concrete elements. Billions of dollars are spent each year just to maintain structurally deficient concrete infrastructure in North America. High maintenance costs justifies the need for innovative materials like GFRP which require minimal maintenance and can last longer in tough environments.

Studies have suggested that over 25% of construction failures happened due to corrosion of metal reinforcement. Non-corrosive and high-strength properties of GFRP adequately resolves problems associated with corrosion of steel reinforcement and lack of design flexibility. Lightweight GFRP rebar makes the transportation and application process more efficient and affordable as fiberglass materials can be installed without heavy machinery.

TUF-BAR fiberglass rebar is ¼ the weight of steel and provides 2x tensile strength. Taken into account these properties, GFRP concrete reinforcement has emerged as an excellent alternative to steel. While GFRP products have an extensive range of applications in construction, it’s ideal to use them in corrosive environments such as highways and wastewater facilities.

Remarkable benefits of GFRP materials lead to improved safety and performance of critical concrete structures: rail LRT, marine structures, bridges, roads, buildings, etc. Increased government spending on highways and bridges and the need for sustainability and safety encourages the construction industry to use GFRP as a leading material to reinforce concrete elements.

To build sustainable infrastructure, structural engineers have to surpass the limitations of traditional materials. If you’re looking to use a cost-effective and durable concrete reinforcement solution for your next project, feel free to explore and select GFRP fiberglass reinforcement.

While the advanced composite industry has successfully proven its worth, one of the challenges is to make these materials more cost-effective. The applications of advanced composites have witnessed steady growth over the last few years. Equipped with the most demanding properties, GFRP construction products can be used to build maintenance-free and durable structures.

The Future Of Composites In The Construction Industry

The Future Of Composites In The Construction Industry

In both new and rehabilitation construction projects, design professionals need to explore the advantages of building environmentally-friendly infrastructure with highly durable and innovative composite materials. It is the need of the hour to develop and implement lightweight, corrosion-resistance, low maintenance, and high strength materials.

Glass fiber reinforced polymer (GFRP) is an example of how advanced composites can completely transform the public infrastructure and help structural engineers design more durable and cost-effective structures.

Advanced composites can be manufactured to provide specific performance properties. Fiber reinforced polymers typically comprises of two major constituents: matrix and reinforced fiber. The collective strength of a composite material is more than the strength of individual strength of constituents.

The manufacturing process, additives, and shape determine the overall properties of reinforcing fibers. Fillers and additives are usually used to adjust the property of composite product to meet design requirements. While composites are thermal and electrical insulators, additives can help achieve additional properties such as resistance to ultraviolet rays and fire.

Phenomenal development in concrete reinforcement technologies now offers exciting opportunities to achieve custom structural properties while resolving conventional problems associated with traditional reinforcement materials such as steel.

GFRP Rebar: An Ideal Solution for Marine Structures

GFRP Rebar: An Ideal Solution for Marine Structures

Glass fiber reinforced polymer (GFRP) reinforcement for civil engineering applications is gaining wide acceptance as a sustainable and long-term alternative to traditional reinforcement materials. One of the distinguishing properties is that they don’t corrode and hence they withstand corrosive environments where steel has a much shorter life span.

Concrete jetties, wharves, bridges, and seawalls are examples of marine structures subjected to environmental elements such as chlorides and weathering. GFRP reinforcement should be used for enhanced durability and longer service life. Design codes have been developed to make GFRP materials more suitable for use in waterside and other critical concrete structures. These composite materials also provide dependable reinforcement solutions to marine concrete rehabilitation projects.

Marine structures play a pivotal role in marine resource exploitation and economic development. Short life span and heavy maintenance are two major concerns that make it difficult for governments to make the most of these structures.

Corrosion and its impact

Corrosion is a natural phenomenon where metals deteriorate rapidly when exposed to moisture and other elements. Steel corrodes rapidly in the marine environment. The construction industry spends heavily on slowing down the deterioration process and repairing the damaged components. Here are some of the factors that cause and accelerate the corrosion process:

  • Chloride-containing elements
  • De-icing salts
  • Sea water
  • Airborne chlorides
  • Carbon dioxide in the atmosphere
  • Sea dredged aggregates

Fiber-reinforced polymers are inherently corrosion-resistance and electromagnetically neutral. These properties strengthen RC structures and help them fight corrosive environments for a long period. The expected lifespan of GFRP rebar is more than 100 years.

Marine construction projects where GFRP rebar is an ideal option:

  • Sewage treatment facilities
  • Retaining walls, seawalls
  • Floating structures
  • Decks, quays, and piles
  • Boat ramps, jetties, and bulkheads
  • Roads, bridges, and pools

Without correct mixing, design, placement, and curing, the durability of concrete can be impaired. The best construction practices and high-quality materials can play a serious role in minimizing the direct maintenance cost and increasing the life cycle of sensitive concrete structures.

Why choose GFRP rebar?

Glass fiber reinforced polymer (GFRP) reinforcement offers promising mechanical and physical properties which make it highly attractive for marine structures operating in aggressive environments such as coastal regions, public infrastructure, and buildings that host sensitive equipment.

How GFRP Can Help Strengthen Canada’s Infrastructure

How GFRP Can Help Strengthen Canada’s Infrastructure

Over the last few years, investment in infrastructure in Canada has considerably increased. Municipalities, provinces, and territories own the majority of public infrastructure which includes bridges, roads, wastewater systems, sports areas, transit systems, and recreation infrastructure. According to Infrastructure Canada 2016, municipal governments own 59.8% while provinces and territories own 38% of public infrastructure.

The federal government has also increased its spending on core public infrastructure over the last decade. These investments are valuable when it comes to minimizing the infrastructure gap and addressing emerging challenges.

Despite the rise in investment in the public infrastructure sector, Canada still needs a long-term strategy to improve the quality, accessibility, and, most importantly, the sustainability of services Canadians use every day. Lack of innovation and willingness to implement new technologies make it difficult for governments to maintain and build long-lasting, maintenance-free structures. The significance of effective, well-designed, and durable infrastructure cannot be undermined.

One of the challenges for all orders of governments is to assess the extent of the infrastructure gap, and how much needs to be invested. The lack of innovation in infrastructure development and the precise data on state and performance of existing structures is hindering economic development. A major portion of funds is invested in the rehabilitation of deteriorated and inefficient structures. The heavy maintenance costs can be dramatically decreased if the construction industry starts implementing materials like GFRP reinforcement and other advanced composite materials.

Importance of concrete infrastructure

Infrastructure refers to the basic systems and facilities required for a nation to function and grow. The quality of infrastructure and how effectively it serves its users greatly impact the economic growth of communities. A country cannot achieve ultimate economic growth if the capacity of its public infrastructure is unable to deal with emerging economic and social challenges.

Railways and roads play a decisive role in accelerating activities and facilitating the flow of people and goods. From telecommunications to transportation, concrete infrastructure helps Canadians adequately accomplish their daily activities. Secure sewage treatment and water supply allow Canadians to enjoy a clean environment and drinking water.

How to strengthen and extend the lifespan of concrete infrastructure

Advanced composites such as GFRP rebar provide governments with a strong and promising alternative to traditional materials. To achieve sustainable concrete infrastructure, it’s inevitable to encourage the widespread use of advanced composites in civil engineering. GFRP reinforcement products can be used both in new and rehabilitation applications. Low maintenance, high tensile strength, lightweight, corrosion resistance, and ease of installation are some of the major characteristics of GFRP construction products.

Canada’s Infrastructure: Opportunities And Challenges

Canada’s Infrastructure: Opportunities And Challenges

The Canadian government encourages and supports the maintenance and development of infrastructure to ensure the citizens have what they need to grow and flourish as a community. Structures like bridges, wastewater facilities and roads are absolutely essential to economic growth and human health. Communication and transportation networks can have a dramatic impact on the economic growth in the region.

However, the infrastructure gap and its impacts are strongly felt by Canadian communities as they put efforts to face economic, environmental, and societal challenges. These challenges are felt more by some segments of society than others. Extreme weather, climate change, and rapid deterioration of concrete threaten existing infrastructure across the country. These factors have an alarming impact on the lifespan, maintenance, cost, and rehabilitation of infrastructure.

In 2013, floods in Alberta destroyed approximately 1000 kilometer of roads and damaged hundreds of bridges. Coastal regions are more vulnerable to the effects of natural disasters, corrosive environment, and rising temperatures.

Economic growth depends on efficient infrastructure

The most critical challenges Canada and the United States face today is the steady deterioration of public infrastructure: sewers, bridges, roads, waterside structures, etc. Governments have to deal with the heavy annual maintenance costs annually just to maintain the existing structures. Bridge delays and thousands of Canadians stuck in their vehicles due to traffic congestion are the areas where innovation and investment can improve productivity and quality of life.

Need for sustainability and foresightedness

Canada needs a long-term and strategic infrastructure investment strategy to develop sustainable and economically viable infrastructure. Since efficient and long-lasting infrastructure is core to economic competitiveness, it’s impossible to achieve sustainable growth without investment and implementing innovative construction strategies.

Unfortunately, public investment in infrastructure couldn’t keep up with our economic and infrastructural needs. For instance, the transportation infrastructure in major Canadian cities can hardly meet pubic demands. The service life of highway structure is only four to five decades which is alarmingly low. A large percentage of public structures either require heavy maintenance or they need to be completely replaced. While the government has to spend billions of dollars in order to upgrade and maintain existing structures, lack of innovation and sustainable construction materials is contributing to this decay.

Opportunities

There is a dire need to develop and implement advanced construction materials to build concrete infrastructure that can last for at least a century with low maintenance. Advanced composite materials like glass fiber-reinforced polymer (GFRP) can help the government replace outdated traditional materials and resolve these longstanding structural issues. For example, GFRP fiberglass rebar is a promising alternative to traditional steel. The government should encourage the construction industry to adopt these advanced products and focus on long-term strategies.
