Superplasticizer - Wikipedia

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.

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. But some of the Portland cement do no behave well with the use of superplasticizers.

Therefore water-cement ratios for High Performance Concretes are very low and in the range of 0.25 and 0.30. In case of Self Compacting Concrete, flowability and self-compaction are the criteria. Conventional Super Plasticizers or Retarding Superplasticizers do not allow high development of strength which is a major requirement in lifting

7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid

Super plasticizers are also used for the production of high strength and high performance concrete. With the use of super plasticizers, flowing concrete could be produced with the water/cement ratio as low as 0.25 or even less. The strength of such concrete was found 120 MPa (1200 kg/cm 2) or more.
