anti-freezing and pumping aid admixture with standard setting agency from China - 2B

GK-2B is a composite which is made up of water reducing,anti-freezing and air entraining etc. Applied to concrete pumping construction in cold weather. Its main features are well pumping and strong anti-freezing ability. On the condition of low temperature, the concrete’s strength can increase continuously, also non-corrosion to steel bar. The anti-freezing and pumping aid admixture satisfies the standard requirement of JC475-2004 and GB18588-2001.

Technical performance

1,The additive dosage of GK-2B is 3-5% of gelling materials, water reducing rate is above 15%, slump’s increased value is above 10cm.

2,It is non-chloride and low alkali, non-corrosive to steel bar.

3,With the addition of GK-2B, which can mend the concrete’s workability,durability and anti-freezing thaw capacity. Furthermore, it will reduce the bleeding rate, so as to be easy for pumping.

4,The GK-2B doesn’t contain free ammonia, harmless and non-contaminate to environment. It can be utilized indoor.

Applied key point

1,The GK-2B should be stringent executed according to the requirement of applicable technological specification for concrete admixture.

2,It should be covered with plastic cloth and grass curtain after casting the concrete in case of the freezing harm when comes low temperature unexpectedly.

3,Recommended use additive dosage according to different temperature conditions as belows:

Package and storage

1,The powder are packed in liner plastic film woven sacks,50kg per bag. The liquid adopt barrel or in bulk

2,Keep them away from open-air and moisture.

3,The validity is two years, overdue concrete can also be utilized after the qualified test.
