Product Description

Product Introduction

ZL-BG bridge bearing epoxy grout is a specialized epoxy grout developed specifically for bridge bearings. It is scientifically formulated using modified epoxy resin, a curing agent, and carefully selected aggregates, offering exceptional features such as high fluidity, superior strength, and excellent bond integrity.

Product Advantages

1. High bond strength: Enables strong adhesion between steel plates and concrete substrates; can bond to damp surfaces, with even better performance in dry environments.

2. Early and High Strength: Achieves compressive strength exceeding 30 MPa within one day, enabling faster beam placement and shorter construction timelines.

3. High Fluidity: Excellent flowability—fills completely in one go, eliminating the need for secondary grouting.

4. Durability: Exceptional durability, resistant to permeation, freezing, water, salt, alkali, and weak acid corrosion;

5. Easy to apply: Simply mix thoroughly before use, with a long working time.
