Description : PNS (Poly Naphthalene Sulphonates) The PNS(Poly Naphthalene Sulphonates) is Superplasticizer for concrete. PNS is made of naphthalene, sulfonic acid, HCHO through sulphuration, hydrolyzation, condensation, neutralization reaction with sodium hydroxide and try to PNS powder. the functions of PNS:
Reduce 10 to 25 percent of cement content when the strength and the slump of the concrete are basically same.
improves the initial slump of the concrete by more than 10cm.
improve the strength by 20 to 60 percent.
economically batch workable concretes with water/cement ratios of 0.3 or less,
batch Silica Fume concrete at low water/cement ratios,
achieve super-fluid, highly workable concretes without excessive set extension. CAS No.: 36290-04-7
Average molecular weight: 25,000-35,000 (by GPC)
S.G (water=1): 0.69
Ionic nature: anionic
Solubility: completely soluble There are four typical grade PNS (Poly Naphthalene Sulphonates) we offer is: DIC05, DIC10 , DIC28 and DICca.

It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on. Mixing Amount Range (Recommended) Powder: 0.75-1.5% Liquid: 1.5-2.5% DICT TECH Company supplies a range of carefully optimised PNS (Poly Naphthalene Sulphonates) superplasticiser raw materials to the Concrete, Drymix and Plasterboard industries.
