Product Description
NSF full name is Naphthalene Sulfonate formaldehyde condensate. Its high purity makes cement paticles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability.

NSF is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing. NSF has a good adaptability to various cements and NSF is no erodent to reinforcing bar and nonpoisonous and pollution-free. NSF has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc.
