Usage:

• Positive temperature lower dosage used for early strength agent is: 2 to 3%.

• Negative temperature lower dosage: -5 °C doped 3 ~ 4%; -10 °C doped 4 ~ 5%; -15 °C doped 5-7%.

• It can be used directly to joint investment and aggregate, mixing time required to extend 2 ~ 3min.

• Every shipment must try experiments with cells, can be used.

Advantages

• The product have powder and liquid two forms.

• This product does not contain chlorine salt, no corrosion on steel, for a variety of reinforced concrete works.

• This product does not contain strong alkaline substances such as K2CO3, haven’t alkaline corrosive to human body, non-accelerating phenomenon and does not affect the operating time of

construction.

• The water-reducing rate is greater than 12% and wide used for portland cement .

• It can be used for concrete work or mortar construction projects on condition of daily minimum temperatures under -20 °C.
