Effect of Superplasticizers to Enhance the Properties of Concrete
The experiments were classified into two phases: the first phase focused on the effects of superplasticizer admixture on workability and compressive strength, and the second phase determined...
Superplasticizer I Concrete admixtures I Super plasticizer - GlobMarble
We recommend to start with 1% by cement weight, then lower the dosage as needed. 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
Superplasticizer: Types, Advantages & Disadvantages - Constructionor.Com
Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes. They achieve a reduction in water content without loss of workability.

Concrete Superplasticizer - High Range Water Reducer in Kingsun
The superplasticizer for concrete has the functions of high-efficiency water reduction, retardation, slump retention and reinforcement. This product has strong adaptability to cement, less dosage, and is easy to use. It is especially suitable for concrete projects that require high-efficiency water reduction and retardation.
- What is a superplasticizer admixture?
- Superplasticizers are water-reducing admixtures used in concrete production to reduce the need for more than 30% of water. They operate at a certain percentage level. One of their main purposes is to prevent concrete from setting too quickly.
- Is a superplasticizer a cure-all admixture?
- A superplasticizer is not a cure-all admixture; it has its own problems, which must be taken into account. Nonetheless, dramatic transformation of stiff concrete into flowing concrete by adding superplasticizer instead of water may be the most significant breakthrough in concrete technology since the development of air-entraining agents.
- What are the superplasticizing admixtures for concrete?
- As for other superplasticizing admixtures for concrete, napthalene formaldehyde condensate or melamine formaldehyde condensate are typically used. The use of such superplasiticizers typically results in a reduction in the amount of water required in the concrete and an increase in the overall strength of same.
- What are plasticizer admixtures?
- These admixtures are known as plasticizers. The combination of organic substances or combinations of organic and inorganic substances which cause reduction in water content for a given workability or give a higher workability at the same water content are known or termed as plasticizer admixtures. These are used for the following proposes: 1.
- Are adsorbed superplasticizers steric?
- Adsorbed superplasticizers, in particular polycarboxylates, provide steric hindrance that prevents close contact between particles, reducing the magnitude of the attractive forces (Lewis et al., 2000; Flatt, 2001).
- How to use polycarboxylate superplasticizer?
- Our product technology and the production equipment of this system have obtained numerous national patents in China. Polycarboxylate Superplasticizer must preferably be added to the mixing water and in case of ready mixed concrete where the product can be added on fresh concrete and in a mixing truck.
