World experience of GFRP rebar use

The first experience of fiberglass application dates back to 1956 in the United States. Massachusetts Institute of Technology had been developing a house made of polymer fiberglass materials. It was intended for one of the attractions in the Disneyland park in California. The house served for 10 years until it was replaced by other attraction and demolished.

When the metal ball-hammer designed for demolition touched the structure, it just bounced off like a rubber ball. The building had to be demolished manually.

In the following decades, it was decided to use polymer composite materials for concrete structures reinforcement. In different countries (the USSR, Japan, Canada and the USA) they conducted developments and testings of innovative product.

Some examples of polymer composite rebar use of foreign experience:

• In Japan, before the mid-90s, there were over a hundred commercial projects. Detailed design and construction recommendations involving composite materials were developed in Tokyo in 1997.
• In the 2000s, China had become the largest consumer in Asia, using fiberglass in various fields of construction — from underground work to bridge decks.
• In 1998 a winery was built in British Columbia.
• GFRP use in Europe began in Germany; it was used for the construction of a road bridge in 1986.
• In 1997, the Headingley bridge was built in the Canadian province of Manitoba.
• During the construction of the Joffre Bridge in Quebec (Canada) decks of dam, pavement and roadblocks were reinforced. The bridge was opened in 1997, and fiber optic sensors were integrated into the structure of the reinforcement to monitor the deformation remotely.
• In the United States it is widely used in the construction of premises for MRI (magnetic resonance imaging).
• It was used in the construction of the world’s largest subways — in Berlin and London, Bangkok, New Delhi and Hong Kong.

Let us consider the world experience of fiberglass rebar use in construction using examples.
