Chemical Admixtures – cement.org
Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement …
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 …
Concrete admixture – Water reducer – Super plasticizer
How to mix with Cementitious Material: Mix concrete/cement with plasticizer for a few minutes, then add water (mix at least 3-5 minutes). You can also add Super plasticizer to the water 10-15 minutes prior to casting (until plasticizer dissolves in water), then mix with dry ingredients.
Superplasticizer – Wikipedia
Superplasticizers (SP’s), also known as high range water reducers, are additives used in making high strength concrete.Plasticers are chemical compounds that enable the production of concrete with ca. 15% less water content. Superplasticers allow reduction in water content by 30% or more.
Concrete Admixtures | Mortar Admixtures | Bonding Agent
Plasticizers or water reducers, and superplasticizers or high range water reducers, are chemical admixtures that can be added to concrete mixtures to improve workability. Unless the mix is “starved” of water, the strength of concrete is inversely proportional to the amount of water added or water-cement …
Concrete Admixtures (Additives)- Types, Selection
Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance transportation of concrete.

High-Range Water-Reducers | Sika Canada Inc.
As a super-plasticizer, Sikament 300 CA may be added with the normal amount of water to produce flowing concrete with up to a 15 cm increase in slump. When used as a high range water reducer, Sikament 300 CA will reduce water requirements by 25-40%, increasing concrete compressive strengths at all ages.
Seven Must-Use Concrete Admixtures (Additives)
Water-reducing admixtures are chemical products that when added to concrete can create a desired slump at a lower water-cement ratio than what it is normally designed. Water-reducing admixtures are used to obtain specific concrete strength using lower cement content.

Types of Admixtures of Concrete & Cement | Chemical, Mineral
A material other than water, aggregates, or cement that is used as an ingredient of concrete or mortar to control setting and early hardening, workability, or to provide additional cementing properties. Admixtures are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time,
