PC-826E Polycarboxylate Superplasticizer Powder

For Concrete (Slump Retention)

PC-826E is a functional powder polycarboxylic acid superplasticizer prepared by special spray drying process from modified polyether polymerization. It is a new generation of concrete slow-release superplasticizer product with high plastic retention, which can be used to prepare high-performance concrete with long retention time, high durability, high flow state, high strength and high impermeability.

Complies with The ASTM C 494 Norm

ASTM C 494, Type D

Advantages：

 High retention plasticity: PC-826E has excellent slump retention, which can effectively adjust the time loss of concrete according to the dosage, effectively extend the transportation and retention time of concrete.

Wide adaptability: PC-826E has good adaptability to all types of cement.

High durability: PC-826E can enhance the firmness of hardened paste, reduce shrinkage and creep properties, reduce cracks, and improve durability.

Green environmental protection: PC-826E does not contain harmful substances, safe and environmental protection.

Technical Data：

Product application：

 PC-826E is suitable for various portland cement concrete systems. Such as in:

All types of concrete

Concrete that needs to maintain its working performance for a long time.

Uses:

1.The recommended dosage of PC-826 is 0.05-0.25% of the gelling material, which should be used together with Huaxuan High-tech KH-204 water reducing agent. The optimal dosage is determined after trial mixing according to the concrete design requirements and actual raw material conditions.

2.In the first way, when conditionally premixed in dry powder, first add PC-826E according to a certain amount, the mixing process needs to ensure the uniform mixing of powder, and then add mixing water to fully stir, to obtain the desired state of concrete;

3.In the second way, PC-826E can first add the corresponding water to make the required solid content liquid, and then add the specific solid content liquid into the concrete according to a certain amount, this addition method has a better effect;

Packaging & Shelf Life:

1.Packaged in paper-plastic composite bags (25kg/bag), the shelf life is 12 months from the date of production. If the shelf life has expired, testing and verification must be carried out before use.

2.Store in a well-ventilated and dry place. Measures should be taken to prevent moisture. Avoiding direct sunlight.After opening, it should be used promptly. If not all of it is used, it should be sealed promptly to prevent it from absorbing moisture and becoming spoiled.
