Product Description:

High purity powder sodium naphthalene sulfonate formaldehyde

     

NZY-FN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. As the main master batch of various kinds of compound concrete admixture, it could also produce series products of concrete admixture which can be suitable for all kinds of project requirement through compounding with other kinds of admixture. This product can contribute to the improvement of project quality and construction efficiency and the reduction of construction cost. It can also improve the process of works.


Applications

1.         NZY-FN is suitable to make high flowing concrete, commercial concrete, pumping concrete, precast and reinforced concrete.

2.         NZY-FNcan be used to make C10-C60 concrete with slump loss between 50mm and 70mm, or C60 concrete with slump between 180mm and 220mm

3.         NZY-FN can be used as raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.

4.         NZY-FNis compatible with Portland Cement, Portland Slag cement, Fly-ash Cement, Portland Pozzolanic Cement etc.
