Superplasticizer

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.

Use of Water Reducers, Retarders, and Superplasticizer

Commonly used WRA is lignosulfonates and hydrocarboxylic (HC) acids. The use of HC acids as WRA requires higher water content compared to the lignosulfonates. Rapid bleeding is a problem for concrete treated with HC acids. Increase of slump is different according to its type and dosage.

High-Range Water Reducer

Chemical admixtures such as high-range water reducers or superplasticizers, viscosity modifying agents, shrinkage reducing and air-entraining admixtures, accelerators, retardants and mineral admixtures have been used in SCC (?ahmaran et al., 2006; Huang et al., 2018; Yu et al., 2014 ).

When are water reducing admixtures used? Water reducing admixtures should be used when a plasticization effect is desired. This is ideal for the production of conventional slump concrete, Self Consolidating Concrete (SCC), ready mix applications, and more. Water reducing admixtures can have an effect on the following properties:

Range Water Reducer

9.2.1 Introduction. In this section the chemistry of the main types of superplasticizers (SPs), also called high-range water-reducing admixtures, is presented. The first part is dedicated to natural polymers, which are rather plasticizers or mid-range water-reducing admixtures. The use of such dispersants dates back to the 1930s.

The Effect of Various Superplasticizers on Ultra High Strength Concrete

High range water reducing admixtures (HRWR) are a particular class of superplasticizers, which are used to manipulate the rheological profile of a concrete slurry. High range water reducing admixture requirements are outlined by ASTM C494 ¡°Standard Specifications for Admixtures in Concrete¡± [ 1 ].
