Costar Retarder 200 is high performance water-reducing and retarding admixture with higher retention time designed to produce high slump concrete with improved workability, durability and also reduces permeability. Costar Retarder 200 is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticizing effect and water reduction are higher if the admixture is added to the concrete aGer 70- 80% of the mixing water has been added.
Features
- High initial slump and retention time
- Improved workability, air entrainment and pumping properties
- It is suitable for use in production of flowing concrete for easier construction with quicker placing and compaction without increasing water content.
- Improved compressive and flexural strength of the concrete both at early and final stage.
- Reduced dimensions of long term shrinkage and creep. Also minimizes risk of segregation and bleeding Chloride-free and suitable for pre-stressing
- Protection of reinforcement steel against detrimental water-borne attack
- Reduces the need for job site adjustment of slump and workability Green products: the production and use of the product does not produce pollution of the natural environment, in line with ISO14000 environmental protection and management of international standards The product is suitable for the production of high-performance concrete, high strength concrete, large flow of concrete in the application performance.
