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.

Addition Rates. ADVA 198 superplasticizer addition rates can vary with type of application, but will normally range from 2 to 15 fl oz/100 lbs (130 to 980 mL/100 kg) of cementitious. In most instances, the addition of 3 to 6 fl oz/100 lbs (195 to 375 mL/100 kg) of cementitious will be sufficient. At a given water/cementitious ratio, the slump
Superplasticizer - an overview | ScienceDirect Topics
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.
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.
Selection of Superplasticizers for High-Performance Concrete
It is observed that certain superplasticizers will perform undesirable at high temperatures. They will develop bad odors, fungi, and bacteria. So, to take the full advantage of superplasticizers, it must be stored in temperatures between 10 and 30 degree Celsius. Dosage of Superplasticizer
- 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 a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve its flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concrete. They achieve a reduction in water content without loss of workability.
- What is a high-performance superplasticizer?
- A high-performance superplasticizer can be prepared by using bio-polymer chitosan as a raw material by chemical performance. This greatly improves the strength of high strength concrete with the presence of silica fume. Hello, I'm Rahul Patil founder of Constructionor.com, I had studied B.E. Civil.
- 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.
- What is PCE superplasticizer?
- PCE superplasticizer is a high-performance water reducing agent that integrates many functions such as high water reduction, high collapse retention, reinforcement, shrinkage, and environmental protection. It is also an ideal admixture for preparing high-strength and high-performance concrete.
- What are the advantages and disadvantages of superplasticizer?
- Advantages of Superplasticizer: Superplasticizers reduces the water content. It reduces the cement content. Also, increases the workability of concrete. It reduces the permeability of concrete. They are easy to placement. Increased long terms. It develops the early strength.
