Delay Set Superplasticizer | Fritz-Pak | Concrete Admixtures
The delay set feature of the products helps keep the first layer of concrete plastic as you work your way around the forms. As a premium superplasticizer, this admixture offers up to 40% water reduction and a Supercizer 7 does not contain hazardous materials and comes packaged in our signature water-soluble bags.
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.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.

- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
- 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 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.
- What is a super plasticizer?
- Classification of Super Plasticizers 3. Uses. Super plasticizers are also called high range water reducers. They are of recent origin and relatively are more effective type water reducing admixtures. They were developed in Japan and Germany during 1960 and 1970 respectively. Chemically they are different from normal plasticizers.
- How a super plasticizer can be used to make concrete?
- With the use of super plasticizers, flowing concrete could be produced with the water/cement ratio as low as 0.25 or even less. The strength of such concrete was found 120 MPa (1200 kg/cm 2) or more. The use of super plasticizers also made it possible to use the fly ash, slag and silica fume to produce high quality concrete.
- Why are superplasticizers used in Indian cementitious mix?
- Superplasticizers are increasingly being used in Indian cementitious mix from the 1980 s onwards as they have proved their credibility in parameters like water and cement reduction apart from workability retention, strength gain, and ease to place and pump.
- What is a high-performance superplasticizer?
- A high-performance superplasticizer can be prepared by using bio-polymer chitosan as a raw material by chemical performance. This greatly improves the strength of high strength concrete with the presence of silica fume. Hello, I'm Rahul Patil founder of Constructionor.com, I had studied B.E. Civil.
