Use Of Composite Materials In Concrete Structures

Use Of Composite Materials In Concrete Structures

The construction industry is gradually becoming one of the leading consumers of composite technology. While the industry started using composite materials in the 1980s, the civil engineering community now shows a high level of confidence in composite technologies for structural applications.

In the past, scientific and logistical issues hindered the widespread adoption of GFRP and other composite solutions. However, extensive research, development of design codes and improved manufacturing technology have made it easy for GFRP manufacturers to produce sustainable concrete reinforcement that meets modern-day requirements.

Why composite technology is imperative to sustainability

Corrosion of steel reinforcement costs billions of dollars every year making it financially difficult for the construction industry to maintain structurally deficient concrete structures such as bridges, roads, waterside structures, water treatment facilities, etc. Corrosion of reinforcement is typically defined as the deterioration of the material when it reacts with its surroundings. GFRP rebar and other fiberglass products are inherently corrosion-resistant adequately solving structural issues associated with corrosion and premature structures.

Impact of corrosion

Corrosion is a natural process that takes place when processed metals start returning to their natural state. It leads to the disintegration of engineered materials into their constituents atoms. The presence of water and oxygen facilitate the electrochemical oxidation of metals, turning steel and other traditional materials into corrosion. Governments should take advantage of corrosion-free GFRP reinforcement to develop or rehabilitate concrete structures and remove the problem of metal corrosion permanently.

Waterside concrete structures are subject to harsh environmental conditions. The abundance of corrosive elements makes it difficult for steel and other traditional materials to reach their expected lifespan. When compared to traditional materials like iron or steel, GFRP rebar demonstrates promising results when exposed to tough natural conditions.

GFRP concrete reinforcement is the solution

Developed countries such as Canada and the United States have already been working on replacing outdated and expensive materials with innovative, maintenance-free, and long lasting composites. Concrete members reinforced with composites can withstand an environment where salts, high acidity, moisture, and other elements are in high concentration. Replacing traditional materials with advanced composites is the only way the construction industry can build structures that can achieve 100 years of lifespan without being heavily maintained.

GFRP construction products such as rebar, rock bolts, dowels, fencing panels, form ties, and lifting anchors are ideal for applications where corrosion and maintenance are prime concerns. Experts from academia and related research industries fully endorse the use of composite materials in both new and rehabilitation applications.

Advanced composites have been developed into environment-friendly construction solutions enabling nations to reduce the carbon footprint. The civil engineering community should put special emphasis on using composite materials to resolve expensive structural problems such as rapid bridge deterioration and premature failure.

From strengthening applications to new construction, GFRP reinforcement is the ideal alternative to steel and other conventional materials.
