1. Product introduction:
JH-Ⅱ high-efficiency retarding pumping enhancer is a composite admixture based on naphthalene sulfonate methylene advanced condensate and reactive polymer. , with 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 28%, the concrete slump is almost no loss in 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 to prepare retardant and pumping requirements of concrete, especially suitable for the use of 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, port construction, slip form , summer construction, etc.
