Use of fiberglass reinforcing materials in concrete structures

The construction industry requires more and more composite materials, becoming their major consumer. Since composites began to be used in the 80s of the last century, engineers and builders have been trusting these new materials that are used in the construction industry.

In previous years, a number of problems in the fields of science and logistics prevented the use of GFRP (fiberglass) composite rebar and other materials based on composites. However, thanks to large-scale research, the creation of design codes and technological improvement of the production process, it became possible to produce fiberglass, which easily reinforces concrete and meets current quality standards.

Why is it necessary to apply GFRP for strength and durability?

Steel rebar corrode. This destructive process annually deprives construction and operating companies of millions of wasted dollars. This causes problems with the material and technical security of the construction industry. Road communications, bridge structures, as well as water treatment and shore protection structures can be severely damaged or even completely destroyed as a result of corrosion. Fiberglass and other materials used in the manufacture of glass fiber exhibit natural resistance to corrosion processes. Therefore, the structures created from them are not subject to premature destruction under the influence of the environment.

How does corrosion affect building structures?

The destruction of metals under the influence of the environment is a common physical process of turning the material into rust. As a result, corrosion-prone structures break down into molecules. The water and air environment interact with metal electrochemically, corroding steel and other vulnerable components. The use of GFRP helps both to create new concrete structures and to restore those already destroyed by environmental influences. This material can stop and completely eliminate corrosion.

Onshore structures made of metal-reinforced concrete cannot function for long in harsh environmental conditions. The use of fiberglass reinforcement significantly extends the life of such coastal structures.

GFRP as an engineering solution

In a number of industrial countries, corrosive metals for concrete reinforcement are already being replaced with strong and resistant composite materials. Reinforced GFRP concrete easily counteracts the negative effects of salt water, moisture, acids, etc. Only a composite design can last a century without repair and ongoing service.

The use of concrete reinforced with composite, as well as various fasteners made of composite materials (dowels, bolts, etc.) are effective everywhere where there is a risk of metal corrosion. GFRP can be used both in construction and in the process of repairing damaged structures.

In addition, modern composite materials are environmentally friendly, since their use can reduce CO2 emissions.

With the help of fiberglass it is possible to carry out the construction and restoration of the most significant bridge structures, so as not to allow them to collapse.

Thus, GFRP is the best replacement for traditional metals. To purchase quality GFRP, contact Kompozit 21 –
