The Effect of Various Polynaphthalene Sulfonate Based
Superplasticizers are developed from different formulations, the most common being Polynaphthalene Sulfonate (PNS), Polymelamine Sulfonate (PMS) and Polycarboxylate Ether (PCE). This study...
Sulphonated Naphthalene Formaldehyde Condensate
Chemistry of chemical admixtures. G. Gelardi, ... R.J. Flatt, in Science and Technology of Concrete Admixtures, 2016 9.2.3.1 Polynaphthalene sulphonates (PNS). PNSs, also known as sulphonated naphthalene formaldehyde condensates (SNFC), were first developed in the 1930s and originally used in textile chemicals and the development of synthetic rubber.
Poly Naphthalene Sulfonate (PNS) - High Range Superplasticizer
Poly Naphthalene Sulfonate (PNS) is also called SNF superplasticizer or naphthalene sulfonate superplasticizer. Its appearance is light brown powder. As a high range water reducing agent, PNS has the features of high water reduction rate, improved concrete strength, and good dispersion effect on cement, etc.

The adsorption behavior of PNS superplasticizer and its
Six commercial cements and a PNS superplasticizer were used for this investigation. Table 1 presents the chemical and Bogue composition of these cements as well as their fineness. Their total Na 2 O soluble equivalent contents range from 0.06% for cement C6 to 0.72% for cement C4.
