Super Plasticizers: Classification and Uses | Concrete Technology
Super plasticizers are used for producing flowing concrete to be used in inaccessible locations, floors or where very quick placing is required. A self levelling and self-compacting concrete is called flowing concrete. Super plasticizers are also used for the production of high strength and high performance concrete.
Experimental Investigation on PCE and SNF Type
C FLOW 175 M is a PCE (Poly carboxylic ether) super plasticizer formulated to reduce the water content of a concrete mixture with a specific gravity of 1.12. The recommended dosage is between 0.4 and 0.8% by weight of cement [ 5 ]. These super plasticizers works as a dispersant by preventing the flocculation of fine particles of cement.

- What is SNF superplasticizer?
- SNF superplasticizer has a good effect on the preparation of large-fluid concrete, and has obvious effects on cast-in-place concrete and prefabricated components with early strength and high strength requirements. It can comprehensively improve various properties of concrete.
- Which concrete projects can SNF superplasticizer be used for?
- SNF superplasticizer is particularly suitable for use in the following concrete projects: liquid concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, natural-cured precast concrete, reinforced and prestressed reinforced concrete, high-strength concrete.
- How many types of superplasticizers are there?
- Superplasticizers are of four types as Sulphonated Naphthalene Formaldehyde (SNF), Sulphonated Melamine Formaldehyde (SMF), Sulphonated Acetone Formaldehyde (SAF), and Polycarboxylate Ether (PC). SNF is obtained from coal tar/petroleum naphthalene where it is converted into sulphonated at high temperature in concentrated sulfuric acid.
- Why does SNF Based super plasticizer have high fluidity?
- SNF-based super plasticizer possesses high fluidity due to reduced monomer and increased molecular weight. Retardation of the cement hydration depends on the molecular weight where the higher the molecular weight, higher the retardation [65, 66].
- How much Sulphonated naphthalene formaldehyde can be used in a superplasticizer?
- The dosage between 0.6 to 2% by weight of cement resulted in minimal retardation. Superplasticizers are of four types as Sulphonated Naphthalene Formaldehyde (SNF), Sulphonated Melamine Formaldehyde (SMF), Sulphonated Acetone Formaldehyde (SAF), and Polycarboxylate Ether (PC).
- What is naphthalene based superplasticizer?
- In addition, naphthalene based superplasticizer has good adaptability with other admixtures and can be widely used as the composition of composite admixtures, such as, pumping agents, waterproofing agents, air entraining water reducing agents and antifreeze agents, etc. More than 15 years of export experience.
