GK-9A Air Entraining Admixture Functional Additives

DESCRIPTION:

GK-9A represents an air entraining agent, based on modified natural resin, resulting in good air entrainment and stable performance. It increases the frost-thaw resistance and impermeability of concrete, and additionally improves the workability observably.

USES：GK-9A is widely used in standard concrete and roller-compacted concrete (RCC) for hydraulic engineering projects.

CHARACTERISTICS：

GK-9A offers the following advantages:

* Water reduction capacity above 6% can be achieved.

* Improves freeze/thaw resistance of concrete;

* Improves workability of fresh concrete and avoids bleeding;

* Improve durability of concrete;

* No corrosion effect on reinforcement;

* Produces desired air void structure in concrete.

PRODUCT DATA

APPLICATION

RECOMMEND DOSAGE

0.003% to 0.2% by weight of cementitious material.

USING METHOD：Dilute GK-9A to 1%-2% concentration, and add into fresh concrete.

NOTES ON APPLICATION：

1. Before using, dilute GK-9A with water (low hardness) in 30 minutes.

2. GK-9A is compatible with all other GK products as following:

— GK Polycarboxylate Water Reducing Admixtures

— GK Pumping Agents

— GK State regulator.

If combined with the above, it is suggested to determine the performance experimentally or consult our technical services department.

3. It cannot be added into polycarboxylate-based water reducers directly, but it can be added into concrete separately in combination with polycarboxylate water reducers, which will not influence its air entraining and stable performance.
