 3.Performance and use

mainly used in concrete construction, so that not only the workability and hydration but also the strength and quality of concrete can be improved.

 When it is the first time to use this product or the concrete kind is changed, ratio need to be tested according to the material used in the construction, so that the best ratio can be found.

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

 4.Packing: 25KG Woven bag with plastic lining

5.non-toxic, non-inflammable, non-explosive.
