ANTI-FREEZING AGENT
Summarize：
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 .
Performance：
appearance: light brown powder
fineness:100% pass the 315 mesh
water ratio:＜3%
the cement net fluidity:≥160mm
Instruction：
Volume vary with the temperature,
-5℃:3%-4%
-10℃:4%-5%
-15℃:5% -7%
-25℃:6%-8%
The concrete temperature in winter :＞5℃
It is unnecessary to add other admitures ,it should be strenth the early regenerative heat conservation for its high fluidity
