Difference Between Plasticizer And Superplasticizer in Civil

Superplasticizer in Concrete. Superplasticizers (SP’s), 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.
