1.  High double bound rentention rate and low cost

2.  Excellent adaptability to cement

3.  1.1%F-108(22%)is added  in concrete ,water reducing rate is above 30%

4.   Improving early strength &strengh after 28days  compressive strength 1day 

       ≥180,3day≥17    7day ≥160     28day≥15

 5.  Greatly reducing W/B ratio ,shrinkage and creep,imporing durability

6.  Low slump loss,slump retention index≥19 mm
