studies on compatibility issues of super plasticizers with
a SNF based Super plasticizer. The water - cement ratio is considered are 0.35 and 0.4. The dosage of Super Plasticizer (Master Glenium ACE 30) started from 0.6% to 1.4% with respect to cement.
Experimental Investigation on PCE and SNF Type
2.1.4 Super Plasticizer Super plasticizer Sikament 2002 NS (SNF) imparts high workability to concrete. 0.5–2.0% by weight of cement is the dosage value recommended by the manufactures. The specific gravity of Sikament 2002 NS is 1.17.
Superplasticizer
Superplasticizers ( SPs ), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
Study of the admixture-cement compatibility for the
It has been found that Polycarboxylate Ether (PCE) based superplasticizers show greater compatibility and economical dosage as compared to Sulphonated Napthalene Formaldehyde (SNF) based...
Concrete Superplasticizer - High Range Water Reducer in Kingsun
The superplasticizer for concrete has the functions of high-efficiency water reduction, retardation, slump retention and reinforcement. This product has strong adaptability to cement, less dosage, and is easy to use. It is especially suitable for concrete projects that require high-efficiency water reduction and retardation.
- 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.
- 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.
- What is naphthalene superplasticizer?
- The naphthalene superplasticizer can improve the workability of concrete, reduce the segregation and bleeding of concrete during mixing, transportation, and pouring, and improve the density and uniformity of concrete. SNF superplasticizer helps to improve the strength and durability of concrete.
- What is the optimum dosage of SNF super plasticizer?
- 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% (from Table 4; Fig. 1).
- 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.
- 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].
