Fibreglass reinforcing bars have been significantly used in some project works in Saudi Arabia, and the following is a detailed description of their application:
Saudi Aramco decided to build a large-scale flood relief channel around the refinery in order to cope with the threat of flooding under extreme weather conditions. Fibreglass reinforcing bars were used as reinforcement for the concrete, replacing traditional reinforced concrete.
Background: Jizan Economic City is located near the sea, and traditional reinforced concrete structures are prone to cracking under the combined effects of extreme stormy weather and wave action, with seawater intruding and corroding the internal reinforced structure, accelerating its deterioration. The project team therefore decided to use glass fibre reinforcing bars to improve the durability and corrosion resistance of the structure.
Scale of application: The spillway is 23,000 metres long and 80 metres wide, using approximately 11,000 kilometres of fibreglass reinforcing bars. This marks one of the largest scale applications of fibreglass reinforcing bars worldwide.
Material advantages: Fibreglass reinforcing bars are lightweight and strong, corrosion-resistant and easy to install and construct. Compared to steel reinforcement, it has higher tensile strength but slightly lower tensile modulus. In a glass fibre reinforcing bar design scheme, the amount of reinforcement required is mainly determined by its tensile modulus.
Construction efficiency: Since the weight of glass fibre reinforcing bars is only 25% of that of steel bars, their handling and positioning are more convenient and require less manpower, thus improving construction efficiency.
In addition to the Saudi Aramco refinery spillway project, fibreglass reinforcing bars have been widely used in other projects in Saudi Arabia. These projects include but not limited to:
Construction field: Fiberglass reinforcing bars can be used in beams, columns, slabs and other structural parts of buildings to improve the overall performance and durability of buildings.
Traffic engineering: In traffic infrastructure such as highways, bridges, tunnels, etc., glass fibre reinforcing bars can be used to replace traditional steel reinforcement to improve the bearing capacity and durability of the structure.
Water conservancy projects: in dams, embankments, irrigation channels and other water conservancy projects, the application of glass fibre reinforcing bars can improve the permeability and durability of the structure, thus extending the service life of the project.
With the continuous promotion of infrastructure construction and the accelerated development of new urbanisation in Saudi Arabia, the market demand for glass fibre reinforcing bars will continue to grow. At the same time, with the continuous progress of technology and cost reduction, the application scope of glass fibre reinforcing steel will be further expanded. In the future, glass fibre reinforcing bars are expected to be applied and promoted in more fields, making greater contributions to the infrastructure construction and economic development of Saudi Arabia.
In summary, glass fibre reinforcing bars have wide application prospects and significant advantages in some project works in Saudi Arabia. Its light weight and high strength, corrosion resistance and easy installation and construction make it an ideal choice to replace traditional steel reinforcement.
