1. Product introduction:
JH-Ⅱ high-efficiency retarder pumping enhancer is a composite admixture based on naphthalene sulfonate methylene advanced condensate and reactive high molecular polymer. It has the functions of efficient water reduction, retardation, slump protection and reinforcement. The product is improved on the basis of the original JH-7 reinforcing agent. Its water reduction rate can reach up to 28%, there is almost no loss in concrete slump for 2 hours, and the 28-day compressive strength is more than 40% higher than the benchmark concrete.
2. Implementation standard: JC473-2001
3. Recommended dosage:
The commonly used dosage of this product is 0.8-1.5% of the cement dosage, which can be used It is suitable for preparing concrete with retarding and pumping requirements, and is especially suitable for use in centralized mixing stations.
4. Scope of application:
This product is suitable for pumping concrete, commercial concrete, fluid concrete, bridges, road concrete, early strength, high strength concrete, waterproofing, large volume concrete, ports Work, slip formwork, summer construction, etc.
5. Packaging and storage:
