1. Product content:
JH-Ⅱ high-efficiency retarder 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 up to 28%, the concrete slump is almost no loss 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 for preparation Concrete with retarding and pumping requirements is particularly suitable for use in centralized mixing stations.
IV. 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 engineering , slip formwork, summer construction, etc.
V. Packaging and storage:
1. The powder of this product is double-packed, 40kg per bag. It should be stored in a dry and ventilated place, protected from moisture and sun.
2. This liquid is packed in barrels, each barrel is 230kg. If there is a small amount of crystallization, it is normal. It will not affect the quality after stirring and melting during use. </p
