Chemicals that improve workability, setting, strength & durability
Admixtures
An admixture is a material added to concrete during mixing to improve or modify its properties such as workability, setting time, strength, durability or water reduction. SDEKAY supplies admixtures from reputed international and domestic brands, compatibility-tested in our lab before bulk production.
Common types of admixtures
- Water Reducing Admixture — reduces water requirement, improves workability and strength
- Super Plasticizer — increases flow / workability without extra water; used in pump and high-strength concrete
- Retarding Admixture — slows setting time; useful in hot weather and long-distance transport
- Accelerating Admixture — speeds setting and early strength; used in cold weather or urgent repairs
- Air Entraining Admixture — introduces tiny air bubbles; improves durability and freeze-thaw resistance
- Waterproofing Admixture — reduces water permeability; for basements, tanks, terraces
