Delay Set Superplasticizer | Fritz-Pak | Concrete Admixtures
Supercizer 7 is compatible with all air-entraining admixtures, calcium chloride and other admixtures. When used with other admixtures, each one must be dispensed separately into the mix. Applicable Standards This product meets the following specifications: ASTM C-494 Type G AASHTO M-194 CRD C-87 Technical Documents Supercizer 7 – Product Bulletin
Types of Admixtures for Concrete - Concrete Network
Admixtures containing microsilica (condensed silica fume) are used to meet high strength and low permeability requirements. Benefits include reduced permeability, increased compressive and flexural strengths, and increased durability.
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.

- 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.
- Do superplasticizers reduce water in concrete mixes?
- The benefits obtained by Superplasticizers in the reduction of water in the concrete mixes are best illustrated by the following examples. With PPC (Flyash based) conforming to IS:1489-part-I-1991. 7 days strength 38.5 N/mm 2.
- Why do we use super plasticizer in concrete?
- Nowadays the use of super plasticizer has become a universal practice to reduce the water/cement ratio for the given workability. The reduction in water/cement ratio increases the strength and improves durability of the concrete. Sometimes plasticizers are used to reduce the cement content and heat of hydration in mass concrete.
- How much does a plasticizer increase workability?
- At the same water/cement ratio, the increase in workability may range from 30 mm to 150 mm slump depending upon the initial slump of concrete, type of cement, content of cement and dose of the plasticizer. A good plasticizer produces fluidity in concrete or mortar in a different way than that of an air entraining agent.
- What is a superplasticizer?
- Er. Kaushal Kishore , Superplasticizers belongs to a class of water reducer chemically different from the normal water reducers and capable of reducing water content by about 30%.
- How many GM of super plasticizer per kg?
- Super plasticizer conforming to IS:9103-1999. With the given requirements and materials, the manufacturer of Normal Super plasticizer recommends dosages of 20 gm per kg of OPC, which will reduce 28% of water without loss of workability. For fly ash included cement dosages will be required to be adjusted by experience/ trials.
