hardening accelerating superplasticizer without chloride suatable for low temperature construction - 1A

GK-1A is a compound non-chloride concrete admixture which is made up of inorganic early strength composition and naphthalene high performance water reducer. It posseses nice early strength and water reducing performance which can improve concrete’s early strength and latter strength under low temperature obviously. Also it meets the high requirements for concrete’s early strength on the condition of low temperature construction.

Technical performance

1,The additive dosage of GK-1A is 1.5-2.0% of the gelling materials, liquid addition is 2-3%,water reducing ratio above 10%.

2,It can boost over 50% if add the 1d strength of concrete of GK-1A, boost over 130% if add 3d strength.

3, Ensure on the same condition of density, which can save above 10% cement if add GK-1A.

4,GK-1A has a perfect flexibility to cement. It can improve the concrete’s workability remarkably, enhance the performance of impermeability,anti-freezing and durability to the concrete.

Package and storage

1,It is packaged by liner plastic woven bag,50kg per sack.

2,It can placed for long time, avoiding from water or humidity.
