Product Introduction

Compared with ordinary glass fiber bars, the glass fiber bars that have undergone sandblasting treatment on their surfaces have significantly improved their physical interlocking performance. The sandblasting treatment forms controllable microscopic concave-convex textures on the surface of the glass fiber bars (roughness approximately Ra = 50-100 μm-1), allowing the concrete slurry to penetrate into them, forming a firm mechanical interlocking. The change from smooth contact to tight embedding significantly enhances the interface friction. A large number of pull-out tests have shown that compared with smooth bars, sandblasting treatment can increase the bonding strength by 20% to 30% when used with ultra-high performance concrete (UHPC), and the effect is even better. The strong bonding force is the foundation of the safety of concrete structures, ensuring the effective transmission of stress - significantly improving the anti-slip and anti-pull-out capabilities, and guaranteeing the anchoring performance. This treatment is particularly suitable for high-corrosion environments such as offshore platforms and can be applied to almost all types and sizes of glass fiber bars.
