Use Method And Matters Needing Attention

 

When used, this product can be mixed with the mixed water into the concrete at the same time, the first mixed with the water after adding the concrete effect is better;

The recommended dosage is 0.05-0.20% of the cementitious material, and the dosage should be determined according to the concrete design requirements and the actual raw materials;

This product can also first add the corresponding water to the required solid content of liquid, and then according to the concrete into the amount;

It should be used with the water-reducing agent

 

Packaging And Atorage

 

Paper-plastic composite bag packaging, 25kg / bag, storage period of 12 months from the date of production, if the shelf life, it must be tested before use;
