Superplasticizer JF-16

Category

Naphthalene series


Detail

Applications

JF-16 is a kind of green product,no pollution, no damage to human beings.

JF-16 has wide serviceability for cement ,obviously enhance effect on concrete.

When under low temperature ,it has no crystallization of sodium phenomenon.

Loss are small for slump. Widely used in all kinds of concrete admixtures

Also for the preparation of the slump heavy rain of 200 mm flow pattern concrete, early strength, high strength requirements of the cast-in-place concrete and prefabricated components, and improve and improve the performance of concrete

Properties

Excellent water-reducing ability. JF-16 can significantly reduce 15% ~25% mixing water in concrete with 1.0%~2.0% dosage.

Early strength, enhance the effect is obvious. Mixed with the product, three days to design strength of 60% to 70%, seven days to 100%, 28 days than blank of concrete strength 30-40%

Concrete slump and the loss is small, 60 min basic don't loss, 90 min loss 10-20%

broad adaptability, workability, cohesiveness for cement.

Can significantly improve the concrete freezing-thawing resisting, anti-permeability, resistance to erosion sulfate, and improve the other physical properties of concrete
