JH-01 is a kind of environment friendly polycarboxylate water-reducing agent that is well received at home and abroad. Main functions:wide adapability,extrem water reducing ratio and better retention.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-01 is 0.4%.
·Main Performance
1. High water-reducing rate: rate can reach over 30% when dosage is 0.4%.
2. Less slump loss of concrete: JH-01 is suitable for concrete’s long-distance transpport and pumping transport.
3. Good adaptability in all kinds of cement and blending admixtures.
4. Low shrinkage,low viscosity and low bleeding rate of concrete: JH-01 can significantly improve concrete’s stability, durability and workability.
5. Extremely small content of chloride and alkali: JH-01 has no corrosion on steel bars.
6. High stability: JH-01 won’t precipitate out in low temperature.
7. Green and environmental protection: free from formaldehyde and other toxic substance.
8. Good econimic returns: comprehensive cost of construction projects is low.
·Scope of Application
JH-01can be widely used in all kinds of concrete projects and cement product,for example:
1. Suitable for compounding long-distance transportation pump concrete.
2.Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3. Suitable for compounding high durable concrete which has impermeability,high ability of keeping collapse and frost-resistance.
4. Suitable for compounding high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC(self compact concrete).
5. Suitable for compounding concrete which has high dosage of coal ash and mineral powder.
