There has been a need for plasticizers ever since PVC (polyvinyl chloride) was patented in 1913. In its unmodified state, PVC is rigid and brittle. Plasticizers are used to make the material soft and flexible. BASF has been a leader in the market for plasticizers and raw materials throughout the history of flexible PVC.

Influence of superplasticizer on strength of concrete - ResearchGate
Davoudi [16] utilized distinctive dose of super plasticizer in his exploration (5-20) litters per m 3 of the concrete to consider the impacts of the super plasticizer on concrete mixtures strength
Super Plasticizers: Classification and Uses | Concrete Technology
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.
- 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 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 admixture?
- Superplasticizers belong to a class of water reducers chemically different from the normal water reducers and capable of reducing water contents by about 30%. The admixtures belonging to this class are variously known as superplasticizers,” “superfluidizers,” “superfluidifiers,” “super water reducers,” or “high range water reducers.”
- When were superplasticizers used?
- In North America they were used from 1974.1’1 The advantages derived by the use of superplasticizers include pro-duction of concrete having high workability for easy placement, and pro- duction of high strength concrete with normal workability but with a lower water content.
- Can superplasticizers reduce water in concrete?
- It has been mentioned already that water reductions of up to about 30% can be achieved in the manufacture of concrete when superplasticizers are incorporated in concrete as water reducers.
- What are the advantages and disadvantages of superplasticizers?
- The advantages of superplasticizers include: (1) production of concrete having high workability for easy placement, and (2) production of high strength concrete with normal workability but with a lower water content.
