JH-02 is a kind of polycarboxylate water-reducing agent which is speciaized in improving concrete’s retention time by special molecular design. It’s well received at home and abroad. Because of it’s stable performance,it’s widely used in all kinds of concrete projects and cement product.

Note: Cement standard P.O.42.5. Recommended dosage of JH-02 is 0.4%.
·Main Performance
1.JH-02 is retention type,high maintainance of concrete,low dosage.It is suitable for concrete’s long-distance transpport and pumping transport.
2. Good adaptability in all kinds of cement and blending admixtures.
3. Low shrinkage,low viscosity and low bleeding rate of concrete: JH-02 can significantly improve concrete’s stability, durability and workability.
4. Extremely small content of chloride and alkali: JH-02 has no corrosion on steel bars.
5. High stability: JH-02 won’t precipitate out in low temperature.
6. Green and environmental protection: free from formaldehyde and other toxic substance.
8. Good econimic returns: comprehensive cost of construction projects is low.
