anti-freezing agent is to be made up of antifreezing, water reducing, air-entraining, keep model .

There are good anti-freezing effect ,high water reducing rate ,keep model,early strength.Without chlorides and ammonia, low-alkali environment-friendly product .

Volume vary with the temperature,-5°C:3%-4% -10°C:4%-5% -15°C:5% -7% -25°C:6%-8% The concrete temperature in winter :>5°CIt is unnecessary to add other admitures ,it should be strenth the early regenerative heat conservation for its high fluidity.
