hardening accelerating and antifreeze additive from China which is an ideal option in cold winter - 2A

GK-2A is composite made up of water reducer,early strength,anti-freezing and air entraining etc. It has the compound function of water reducing,anti-freezing and early strength. With the addition of GK-2A, it can mend the concrete’s formation of pore, reduce the free water in the concrete and lower the ice point of concrete. Also it can promote the concrete’s aqueous ability on the condition of low temperature ambient, so as to meet the anti-freezing demand of concrete. Early hardening and anti-freezing admixture is an ideal option for concrete construction in cold winter which implement the standard requirement of JC475-2004 and GB18588-2001.

Technical performance

1,The additive dosage of GK-2A is 3-5% to the gelling materials, water reducing rate above 10%.

2,It is non-chloride and low alkaline, possess the double function of anti-freezing and water reducing ,also non-corrosive to steel bar. By the way of controlling additive dosage, it can satisfy the constructed requirements under diverse temperature ambient.

3,It can ameliorate the workability and durability of concrete when add some GK-2A, meanwhile including the ability of anti-freezing and anti-thaw.

4,The GK-2A doesn’t contain free ammonium, which is non-contaminate and harmless to environment. It can be used indoor as well.

Practical key point

1,Pls proceed construction complied with the rules of applied technological specification of concrete admixture.

2,It should be covered with plastic cloth and grass curtain after casting the concrete. Prevent from being cold immediately, otherwise there might be a huge loss of concrete’s strength ability.

3,Recommended the usage of addition dosage according to different temperature conditions as belows:

Package and storage

1,With liner plastic woven packaged,50kg per bag.

2,Stored in shady and dry depot, guard against humidity.

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