Poly naphthalene sulfonate is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing. It has a good adaptability to various cements and PNS is no erodent to reinforcing bar and nonpoisonous and pollution-free. It 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.

Poly Naphthalene Sulfonate Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.

Poly Naphthalene Sulfonate Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
