Use of Water Reducers, Retarders, and Superplasticizer
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
Choosing the Right Superplasticizer for Your Concrete
Standard versus Premium. Fritz-Pak manufactures two strengths of superplasticizers. Our Supercizer 1 and Supercizer 5 are standard plasticizers formulated to increase the slump of your concrete by up to six inches and reduce the water requirements by 20%. These products are excellent choices for smaller corrections to the mix on the job site.
MasterPolyheed 8126
superplasticizer developed primarily for use in pumped concrete. It contains polycarboxylate ether polymers and is specially formulated to give exceptionally high water reduction and significantly improved slump retention compared to conventional superplasticizer. MasterPolyheed 8126 is free of chloride and has
Superplasticizer
Superplasticizer. Superplasticizers ( SPs ), 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.
Selection of Superplasticizers for High-Performance Concrete
By only focusing on the solid content it is recommended to use naphthalene superplasticizers when compared with the melamine. The naphthalene superplasticizers are marketed with a solid content from 40 to 42 percent. The melamine superplasticizers are marketed for a solid content of 22 to 30 %.
- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve its flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concrete. They achieve a reduction in water content without loss of workability.
- What is a superplasticizer used for?
- Superplasticizers are mainly used in pumping concrete, casting heavily reinforced members and precast elements of concrete. Advantages of Superplasticizer: Superplasticizers reduces the water content. It reduces the cement content. Also, increases the workability of concrete. It reduces the permeability of concrete. They are easy to placement.
- When should you use a premium superplasticizer?
- You can use a premium superplasticizer when you need a more extreme change in the slump or if you have a project that requires more compressive strength after the concrete has set. Superplasticizers are formulated to reduce the water content of your concrete mix, but during the summer months, this can make your concrete set up even faster.
- Do superplasticizers work in Portland cement?
- Superplasticizers are used to fluidify the concrete in the field. Most of the superplasticizers helped to maintain high slump values for a time of 30 to 45 minutes. But some of the Portland cement do no behave well with the use of superplasticizers. This problem is understood only by the detailed study on the mode of action of superplasticizers.
- What is high-efficiency concrete superplasticizer?
- High-efficiency concrete superplasticizer is a chemical admixture that can significantly improve the workability of commercial concrete and significantly reduce its mixing water volume. It is one of the important products in the pillar industry of new building materials.
- What are the advantages and disadvantages of superplasticizer?
- Advantages of Superplasticizer: Superplasticizers reduces the water content. It reduces the cement content. Also, increases the workability of concrete. It reduces the permeability of concrete. They are easy to placement. Increased long terms. It develops the early strength.
