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.
Sika ViscoCrete TS-100 | PCE based Super-plasticizers
Sika ViscoCrete TS-100 is a third generation superplasticizer for high performance concrete. It was particularly formulated for the production of precast tunnel segments, targeting the high demands regarding slump retention, very low water/binder ratios, use of double or triple blend mixes (cement, GGBFS, PFA and/or microsilica) and high degree of compaction.
SikaPlast-398 SF | Super Plasticizers
SikaPlast-398 SF is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. SikaPlast-398 SF conforms to type G when used at 0.8 - 1.0% dosage, depending on cement type used. SikaPlast-398 SF combines different modes of actions. By adsorption on the surface of the fines and keeping them

Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.
Selection of Superplasticizers for High-Performance Concrete
Selection of Superplasticizers for High-Performance Concrete Home / Concrete Technology / Concrete Admixtures Reading time: 10 minutes Superplasticizers are used to fluidify the concrete in the field. Most of the superplasticizers helped to maintain high slump values for a time of 30 to 45 minutes.
- Is superplasticizer a good concrete admixture?
- From the results of the study pr esented of superplasticizer. However, very high dosages of concrete. admixture. However, effectiveness is higher for superplasticizer concrete than normal concrete. Compressive strength is improved by superplasticizer. On desired characteristic strength.
- 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.
- Can super plasticizers reduce water content in concrete mix?
- The use of super plasticizers can permit the reduction of water in the concrete mix upto 30% without producing any ill effect on the workability of the concrete i.e. without reduction in the workability of concrete, where as normal plasticizers with doses upto 0.1 to 0.4% by weight of cement can reduce water content from 5 to 15%.
- What is a superplasticizer in cement?
- According to ASTM C494, superplasticizers are linear polymers that possess a sulfonic acid group. The addition of superplasticizers into a mix neutralizes the surface interaction among the cement particles and thus, reduces the viscosity of cement paste (free from agglomeration) resulting in reduced pore volume.
- What is a super plasticizer?
- Classification of Super Plasticizers 3. Uses. Super plasticizers are also called high range water reducers. They are of recent origin and relatively are more effective type water reducing admixtures. They were developed in Japan and Germany during 1960 and 1970 respectively. Chemically they are different from normal plasticizers.
- Does superplasticizer dose affect concrete performance?
- The past researchers have been underscored the use of chemical admixtures imparts the desirable properties to concrete in both fresh and hardened state. This paper has been made an attempt to study the influence of superplasticizer dose of 0.6, 0.8, 1.2, 1.8 and 2.5 percentage on performance of concrete.
