Description:
General 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.
