Superplasticizer: Types, Advantages & Disadvantages
1. Superplasticizers reduces the water content. 2. It reduces the cement content. 3. Also, increases the workability of concrete. 4. It reduces the permeability of concrete. 5. They are easy to placement. 6. Increased long terms. 7. It develops the early strength. Disadvantages of Superplasticizer: 1.

without super plasticizer added concrete. Super plasticizer permitted a significant water reduction while maintain the same ... (PNS), the molecular structure of which is
Experimental Studies on Properties of Concrete due to
The dosages of super plasticizer were adopted as 0.25% by weight of cement. To study the effect of super plasticizer the experiment has been divided into four series namely workability...
Study on different types of Super plasticiser used for Self
Super plasticizer: To improve workability, high range water reducing naphthalene based and polycarboxylic based super plasticizer is used. SP dosages of 3%, 4% and 5% were found insufficient to produce the required workability such as flow- ability and resistance to segregation. However, mixes with super
Concrete Super Plasticizer Pozzolan, Fritz PNS Description
Complete Description, Concrete Super Plasticizer Pozzolan, Fritz PNS. We've accumulated three concrete super plasticizers. This is a mid price range super plasticizer for use in Portland cement products such as concrete, mortars, grouts, etc. It is one type of pozzolan performance and strength enhancer for concrete.
- What is PNS superplasticizer used for?
- Besides, PNS superplasticizer can be used in combination with other various admixtures, and the price is relatively cheap. The naphthalene based superplasticizer is commonly used to formulate high fluidity concrete, high strength concrete, high-performance concrete. This superplasticizer has a strong dispersion on 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 poly naphthalene sulfonate superplasticizer?
- The poly naphthalene sulfonate superplasticizer can comprehensively improve various properties of concrete, and i t can be applied to high compressive strength integral heavy concrete and reinforced concrete, fine concrete, dense cladding concrete, thin plate structure and other complex concrete structures.
- What is naphthalene superplasticizer?
- Therefore, naphthalene superplasticizer can greatly improve the fluidity of the cement mixture and the slump of the concrete. At the same time, PNS naphthalene superplasticizer can also greatly reduce water consumption and improve the workability of the concrete.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- What is poly naphthalene sulfonate (PNS)?
- Poly Naphthalene Sulfonate (PNS) is also called SNF superplasticizer or naphthalene based superplasticizer or naphthalene sulfonate superplasticizer. Its appearance is light brown powder.
