Concrete Admixture(Super Plasticizer) FDN

 2.The main technic standard

Item	Parameter
PH value (1% water-solution)	7--9
Cement slurry fluidity,    mm	180-220
Content of sodium sulfate,    (%)    ≤	18

 3.Performance and use  1)put this product which’s weight is 0.5-1.2% of concrete’s weight into concrete, 12-25% water can be saved.

 2) provided water and cement ratio keep the same, if add FDN, the height on which the cement initially collapse can be 10cm higher at least

3)if FDN is properly added, the strength of mortar and cement can be enhanced by 40-80% within 3days, 20-60% within 28days. Of course it still works on the strength for long term.

4.Packing: 25KG Woven bag with plastis l

4) Provided the strength of cements and slump keep the same, if added FDN water needed can be saved by 10-25%.

5)adding FDN can improve the workability and other mechanical characteristics. This can enhance it’s alibility to resist compression contraction.

6)FDN is widely applicable for cements builing,especially for the following: fluid cement, plasticized cement,steamed cement,water-tight cement,water-proof cement, prefabricated cement,prestressed reinforced cement and high strength cement. But the adaptability to different kind of cement is different.
