High Range AE superplasticizer JF-11
Applications
When JF-11 is added in the concrete, it can produce well-proportioned small air-bubbles which is difficult to destroy after stirring.
JF-11 is suitable for concrete with air content.
JF-11 is used for harbor, pier, water conservancy project, highway pavement and etc.
Properties
According to the air content requirement (3-5%), JF-11 must be tested in the laboratory before it confirm the suitable content. And the range of power JF-11 is 0.5~1.0%, the range of liquid JF-11 is 1.0-2.0%.
Impervious gradation of mortar can reach to P8-P10，impervious gradation of C30 concrete can be P14, the highest impervious gradation of concrete can reach to P40.
JF-11 is suitable for mixing common concrete, concrete for hydraulic structure, fluid concrete and commercial concrete of C30-C50, especially fit concrete work with high life requirement and freeze-melt resistance.
JF-11 apply to portland cement and portland blast furnace cement.
Dosage of JF-11 should be increased when it is mixed with pulverized fuel ash.
