Product Description



I,Features and Applications  
For preparation flow state of concrete, early strength, high strength requirement of cast-in-situ concrete and pre-cast component, have very good use effect, can improve and improve concrete performance. naphthalene formaldehyde widely used in roads, Bridges, tunnels, DAMS, ports, electricity, water conservancy and civil engineering, pipe and natural curing to the system components, etc.
II, Performance 
1,Powder or liquid. The powder appears to be brownish yellow, and the liquid appears to be tan. Both are nontoxic, odorless and incombustible. 
2,Blend dosage 0.3-1.5% for powder (as cement amount), recommended blend dosage 0.75% for powder (as cement amount). 
3,When added into concretes:   While keeping the cement consumption and slump unchanged, water reduction will reach more than 22%, and increase 1d compressive strength of concrete up to 60-100%, 3d compressive strength up to 50-90% and 28d compressive strength up to 30-50%, to be further reinforced in later period.   
A.  While keeping the water-cement ratio and water consumption unchanged, concrete slump can be increased by more than 120mm.  
B. While keeping the slump and compressive strength basically unchanged, consumption of cement can be saved by over 18%.  
C. The durability and other properties of concrete can be evidently increased and improved.


 III,Application Method and Notice 

1,Blend dosage range is 0.3-1.5%, and application blend dosage is 0.5-1.2%. Appropriate blend dosage can be selected according to project object and the materials used during application. 
2,FDN-02 powder is recommended to be applied in solution. It can be used in dry form, but make sure mix it thoroughly with concrete. 
3,If this product is applied with adoption of stagnant water blending method or post-blend approach, water reduction and dispersion will be better. 
4,This product can be formulated with concrete additives of other varieties. It can be “double blended” with blending materials such as fly ash, ground slag, etc. But the blend dosage shall be calculated based on the total of cementing materials. 
5,When this product is used for the first time or cement variety is changed, concrete trial preparation shall be conducted according to the adopted materials and construction requirements in the field. Construction mixing rate shall be adjusted based on testing result to serve as instruction for construction blending.





Packaging & Shipping





 IV,Packing, Transportation and Storage 
1,Powder pack: woven fabric bag with plastic liner. Net weight: 25kg±0.1kg or 50kg±0.2kg or 650kg±1.0kg Liquid pack: airtight plastic or iron drums, or tank car in bulk.   
2,Cautions should be taken to prevent from being torn by sharp-ended objects while packages are being transferred or delivered. When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect. 
3,It should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective in one year. After the expiration date, it can be used again if the testing results fall within the established range.
