This system innovates prestressed concrete beam construction by using Basalt Fibre Reinforced Polymer (BFRP) bars instead of traditional steel. It includes a T-frame structure with a spandrel beam and steel formworks. BFRP bars are pre-tensioned using a hydraulic jack, casting concrete around them, and then releasing the prestress to reinforce the concrete. The system aims to improve durability and reduce corrosion concerns compared to steel prestressing methods.

- Environmental Sustainability: Reduces environmental impact by BFRP bars, which are non-corrosive and have lower carbon footprint compared to steel.
- Infrastructure Durability: It mitigates the corrosion issues and hence enhance the lifespan of infrastructure
- Cost Efficiency: Reduces maintenance costs over the lifetime of structures due to BFRP's durability and lower maintenance requirements.
The proposed system offers a unique approach to prestressed concrete beam construction by integrating Basalt Fibre Reinforced Polymer (BFRP) bars. Unlike traditional steel methods, it eliminates the need for end blocks, simplifying construction and reducing costs. The use of BFRP bars enhances durability by mitigating corrosion issues and offers potential for widespread application in infrastructure projects. The system's design includes innovative features such as adjustable mechanisms and stiffener plates, tailored for efficient and reliable prestressing operations using non-metallic, high-strength BFRP materials.
