Superplasticizers for Concrete - MDPI
for concrete with higher efciency in terms of water reduction with respect to polycarboxilate-based admixtures and characterized by a higher compatibility upon different cement types/production batches than NSF-based admixtures. 2. Materials and Methods Concrete mixes manufactured by using 13 different cement types produced by different cement
Effect of Functional Superplasticizers on Concrete
Early-strength polycarboxylic acid superplasticizer (F, 20%) was purchased from Sika (Zurich, Switzerland), and naphthalene-based water-reducing agent (NF) was purchased from . (Shandong, China).

The current work investigates the fluidity and the loss of the flow rate of cement paste and mortar over time, as well as the pore structure and compressive strength of concrete and mortar in the presence of functional polycarboxylic acid high-performance water-reducing agents.
Concrete Plasticizer for Sale in Kingsun Factory
The concrete plasticizer, also known as superplasticizer, refers to an chemical additive that can highly improve the workability, strength, durability, and other properties of concrete. They are essential for the production of high-quality concrete structures in the construction industry.
Concrete Superplasticizer Market | Global Industry Report, 2024
Concrete superplasticizers are segmented into five product types – sulfonated naphthalene formaldehydes, polycarboxylic acids, sulfonated melamine formaldehydes, lignosulfonates, and others. The market can be further classified on the basis of application into ready mix, precast, self-compacting, and high performance.
- What is a high range concrete superplasticizer?
- High range concrete superplasticizers have a strong dispersing effect on cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of the concrete.
- What is concrete superplasticizer?
- Concrete superplasticizer is also known as high range water reducer. They belong to the synthetic water-soluble organic substances that reduce the amount of water require to achieve a certain stability of concrete, reduce water-cement ratio, reduce cement content and increase slump.
- Do superplasticizers improve the fluidity of concrete?
- 5. Conclusions Superplasticizers are chemical additives that can significantly improve the fluidity of concrete. They work by reducing the surface tension between cement particles and water, thereby reducing the amount of water required to improve the workability of concrete.
- What is Kingsun concrete superplasticizer?
- Therefore, Kingsun concrete superplasticizers can be suitable for prefabricate and cast-in-place reinforced concrete in various industrial and civil construction, water conservancy, transportation, port, municipal and other projects. Besides, it can be used for the water-reducing and reinforcing components of various composite admixtures.
- What happens if the superplasticizer dosage is large?
- When the superplasticizer dosage in concrete is large (over-dosing), the retardation is slightly retarded, but the early strength of the hardened concrete is not delayed. It can greatly reduce the amount of water and significantly increase the strength of concrete at various ages.
- What were the first superplasticizers?
- The first commonly employed superplasticizers were lignosulfonates, although their water reduction was limited and had a considerable influence on the flowability of concrete .
