High Range Water-Reducing and Set-Retarding Admixture – Aqueous Solution
Description
AD-TEK HWRRe is a third-generation composite superplasticizer (hyperplasticizer) for high quality concrete and mortar, when superior performance is required.
AD-TEK HWRRe can significantly extend concrete mixes transportation time and workability, dramatically reduce mixing water, promoting excellent flow characteristics and high ultimate strengths of concrete.
AD-TEK HWRRe is in accordance with Australian Standard AS 1478.1 – 2000 as a High Range Water Reducing and Set Retarding Admixture.
Uses
- Construction sites which need extended transportation time and reliable workability in hot weather
- Concrete requiring extremely high water reduction
- High strength concrete
- Concrete with the highest requirements on durability and quality
- Pumped concrete
- Self compacting concrete
Benefits
- High water reduction
- Increased strength
- Slump retention
- Super workability without segregation
- Low permeability, high durability concrete
- Low shrinkage and creep – reduced risk of cracks
- Easy to pump concrete
- Suitable for the production of self compacting concrete
Technical Data (typical)

Dosage
The recommended dose rate is between 300 – 1000 ml per 100 kg of cement binder.
For self compacting concrete, the typical dosage is 700ml -1800ml per 100 kg of cement binder. Site trials are recommended to determine the actual dosage rate.
Application
The maximum plasticizing effect or water reduction is obtained if AD-TEK HWRRe is added into concrete after cement is wetted out. Thorough mixing is required for complete dispersion throughout the mix.
Packaging, Storage and Shelf Life
AD-TEK HWRRe is available in 20-litre containers, 1000-litre cubes and in bulk.
AD-TEK HWRRe should be stored at a temperature between 5ºC and 40ºC. In an unopened original container, it has a shelf life of one year.
