    ·

    Superplasticizers are additions that allow a given degree of workability to be obtained at a reduced water/cement ratio. The ratio may be reduced by up to 20% in the presence of, for example, sulphonated naphthalene formaldehyde condensate, which is absorbed at the solid/liquid interface. They have the effect of neutralizing the surface attractions between individual particles of the cement, causing them

  • Sodium Naphthalene Sulfonate Formaldehyde - SNF/PNS

    Sodium naphthalene sulfonate formaldehyde (SNF/PNS/FND/NSF), also called polynaphthalene sulfonate or naphthalene based superplasticizer, is the light brown powder. It is made of naphthalene, sulfuric acid, formaldehyde and liquid base, and undergoes a series of reactions such as sulfonation, hydrolysis, condensation and neutralization, and then dried into powder.

    Many important characteristics of concrete are influenced by the ratio of water to cementitious materials used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond
