History of glass fiber reinforced concrete
In the 1950s, for the first time in the Soviet Union and then in the United States, research was conducted on the use of steel fibers in concrete, which showed a reduction in the concentration of stress at the crack site.

Fiber concrete, which is called and produced under different names in the world, consists of different reinforcements such as glass fibers, aramid fibers and carbon fibers.

Fiber concrete is one of the most widely used materials in cold regions such as North America, Canada and some European countries. The use of fiber concrete has become very common and it is used in several bridges in Japan and in European countries. It is used especially in Japan due to the resistance of fibrous concrete to corrosion in bridges and facade walls.

Today, many universities around the world are trying to use and develop this knowledge in the construction industry.

What is a GRC?

Fiberglass-reinforced concrete is actually a type of composite that increases its tensile and compressive strength by using reinforcing fibers inside the concrete mix. This composite compound has high integrity and cohesiveness and allows the use of concrete as a formable material to produce durable curved surfaces. Fiber concrete also has a high energy absorption capacity and does not disintegrate easily under impact loads.

The historical evidence of this technology is the use of thatch in the construction of the building. In fact, fiber concrete is an advanced type of this technology in which new natural and synthetic fibers have replaced straw and cement has replaced mud used in the straw composition.
