JH-03 High performance water-reducing type: Polycarbpxylate Superplasticizer
JH-03 is a kind of eco-friendly polycarboxylic water-reducing agent that is well received at home and abroad. It specialized in high water-reducing rate and good concrete retention at the same time. In addition, it can be used in all kinds of concrete and cement’s products and projects with its widely adaptability and stable performance.

Note: P.O.42.5 standard cement is used in the test, dosage of JH-01 is 0.4%
·Main performance
1. High water-reducing rate: water-reducing rate can reach over 28% when dosage of JH-03 is 0.4%.
2. Less slump loss of concrete: it’s suitable for concrete’s long-distance transpport and pump transport.
3. Good adaptability: it can be used in with kinds of cement and blending admixtures.
4. Low shrinkage, viscosity and bleeding rate of concrete: JH-03 can significantly improve concrete’s stability, durability and workability.
5. Extremely small content of chloride and alkali: JH-03 has no corrosion on steel bars.
6. Stability in use: JH-03 won’t precipitate out in low temperature.
7. Green environmental protection: free of formaldehyde and other toxins.
8. Good econimic returns: engineer total cost is low..
·Scope of application
JH-03 (50%) can be widely used in all kinds of concrete and cement’s products and projects, 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.
·Usage
1. Recommended dosage (by weight) is 0.25%-0.80% of the cementing materials. The best dosage should be determined according to the particular project conditions and actual materials.
2.JH-03 can’t be used with naphthalene water reducer. Compatibility test should be done when JH-03 is used with other additives.
3. Precise measurement: heavy doped, no adding and mixed with error should be avoided.
·Storage and important notes
1. JH-03 should be store at temperature from 0℃-40℃. Exposure to direct sunlight and rain must be avoided, and mixed with clutter should be avoided.
2. JH-03’s shelf life is as long as 180 days. New test should be done when it beyond warranty period, and can be used when it’s qualified.
3. JH-03 is non-toxic, non-polluting and non-edible. Avoid contact with eyes and allergies. If sprayed in eyes flush with plenty water and check with doctor in hospital
