Composite antifreezing agent concrete water reducing agent
•Introduction
Composite Anti-freezing Superplasticizer is a non-corrosive, non-chlorine compound antifreeze admixture which compounded with water-reducing, early-strength, reducing the freezing point, preventing freezing damage etc.
It is suitable for the winter construction (in ambient temperatures ranging from -10 °C degree to -20 °C degree) of common concrete, pumping concrete, large volume concrete and ready mixed concrete.

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.
• Composite antifreezing agent does not contain chlorine salt, no corrosion on steel, for a variety of
reinforced concrete works.
• Composite antifreezing agent 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.
