ZY-J Interface Agent
ZY-J Concrete Interface Agent is a high-performance, two-component polymer-modified cement-based material, primarily composed of cement, polymer emulsion, mineral admixtures, cement superplasticizer, aggregates, and more. When in use, components A (solid) and B (liquid) are mixed together in a specific ratio. ZY-J leverages cutting-edge modification technologies currently available for cement-based composites, particularly integrating multiple advanced techniques designed to strengthen the concrete interface. This approach significantly enhances the transition zone at the bond between new and existing concrete, thereby improving the interfacial adhesion between the two materials.

Product Description
Product Introduction
ZY-J Concrete Interface Agent is a high-performance, two-component polymer-modified cement-based material, primarily composed of cement, polymer emulsion, mineral admixtures, cement superplasticizer, aggregates, and more. When in use, components A (solid) and B (liquid) are mixed together according to a specific ratio. ZY-J integrates cutting-edge modification technologies currently available for cement-based composites, particularly leveraging multiple advanced techniques designed to strengthen the interfacial transition zone within concrete. This innovative approach significantly enhances the transition area at the interface between new and existing concrete, thereby improving the bond strength between the two materials.
Product Advantages
1. High interfacial reinforcement effect strengthens or even eliminates the transition zone within concrete, enhancing chemical bonding at the interface.
2. High fluidity and permeability enhance interfacial mechanical adhesion;
3. High water retention to prevent the formation of locally high water-cement ratio interfaces;
4. The curing process features minimal shrinkage, preventing cracking at the interface;
5. Elastic modulus, thermal expansion coefficient, and dry-wet deformation of hardened concrete are comparable to those of new and old concrete;
6. High body strength and bonding strength;
7. For high-performance polymer-cement composite materials, it exhibits excellent durability and boasts high long-term strength;
8. Construction is convenient and simple—simply mix the two components, (solid) A and (liquid) B, in a specific ratio at the construction site to create a slurry of appropriate consistency for immediate use.
