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.
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.
