Superplasticizer in Concrete

Jun 30, 2021  A superplasticizer is not a cure-all admixture and comes with its own problems that need to be taken into account. But still, a dramatic transformation of stiff concrete into flowing concrete can occur when a superplasticizer is used instead of water. Types of Superplasticizer.

Use of Water Reducers, Retarders, and Superplasticizer

Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture. Admixtures are used to modify the properties of concrete or mortar to make them more suitable to ...

Superplasticizer - Wikipedia

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. These additives are employed at the level of a few weight percent.

SuperPlasticizers High Range Water Reducers.Types, Uses ...

Jun 18, 2018  The mechanism and properties of superplasticizers are very similar to plasticizers. Researches state that the water content of concrete can be reduced from 15 to 30% without reducing the workability of concrete. So they are also called as high range water reducers. They are developed in the 1960s in Japan and later in Germany.
