Physical & Thermal Specifications.
Chemical, thermal, and material properties supporting long-term concrete stability.
Material Composition
Primarily composed of high-strength Boron-free E-CR glass fibers bound in a high-grade chemical-resistant epoxy resin matrix, providing maximum resistance to alkaline cement environments.
Thermal Coefficient
Longitudinal CTE is 9.0 x 10^-6 /°C, matching concrete expansion rates to eliminate thermal shear stress. Transverse CTE is 22.0 x 10^-6 /°C, maintaining internal structural consistency.
Electrical Insulation
GFRP is completely dielectric, offering an electrical volume resistivity greater than 10^12 ohm-cm. This prevents galvanic loop currents and track-current leaks in heavy rail tunnels.

Technical FAQ.
What standard testing codes govern GFRP rebar parameters?
Our composite rebars are designed and tested according to ASTM D7957 (Standard Specification for Solid Round GFRP Bars for Concrete Reinforcement) and are designed to IS 18256:2023 specification.
What is the shear strength of GFRP rebar?
GFRP rebar features a transverse shear strength exceeding 150 MPa, in compliance with ASTM D7617 test criteria. This ensures adequate resistance to lateral forces inside the reinforced concrete element.
How does GFRP bond strength with concrete compare to steel?
Due to the external spiral-wound fiber wrap and sand-coating texture, GFRP bond strength exceeds 15 MPa, which matches or exceeds standard deformed steel rebars, preventing slippage inside the concrete matrix.
