Detailed Product Description

1, FDN is widely to be applied to make flowable, strong or steam-curing concrete., its minimum working temperature can be as low as 0C.

2, FDN can reduce water more than 25%. It effectively increases concrete fluidity and reduces water peneteation and segregation. Therefor, it improves concrete placement and makes concrete wasy to use and compacting.

3, It can be used widely in the different variety of cement.

4, It has less effect on the initial and final setting time, the difference in setting time generally is less than 1 hour.

5, No toxic, smell and radiation. No corrosion to steel bar.no flammable and explosive matterial. It is not hazardous substance.
