Composite Anti-freezing Superplasticizer

Description

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.


Standards Compliance

It complies with ASTM C 494, Type F,G and E BS EN 934-2


Main Use & Advantages

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.

●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.
