Experimental Investigation on PCE and SNF Type
The optimum dosage of SNF Super Plasticizer is 0.5 and 25% water reduction from the analysis and it is used to determine the strength results of the Perlite added concrete at a replacement percentage of 10, 15, 20 and 25% [ 4] (from Table 4; Fig. 1 ).

Sodium Naphthalene Formaldehyde (SNF-Superplasticizer for Concrete) INTORDUCTION: CAS Code: 36290-04-7 HS Code (CN): 38244010 SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, NSF, etc…)
- What is SNF superplasticizer?
- SNF superplasticizer helps to improve the strength and durability of concrete. By reducing the pores and cracks in concrete, reducing water penetration and erosion, the service life of concrete structures can be extended. Sodium naphthalene superplasticizer can also improve the performance of cement.
- 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 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.
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- 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 the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
