HyperplastPC690
High range water reducing admixture with workability retention properties
Hyperplast PC690 is a high performance superplasticising admixture based on polycarboxylic ether polymers with long chains specially designed to enable the water content of the concrete to perform more effectively.
This effect can be used in high strength concrete and flowable concrete mixes, to achieve highest concrete
durability and performance.
- Optimises cement utilisation.
- High density and impermeable concrete through very high water reduction.
- Improves shrinkage and creep behaviours.
- Minimizes segregation and bleeding problems by improving cohesion.
- Higher early and ultimate compressive strengths.
- Increases durability and resistance to aggressive atmospheric conditions through reduced permeability.
- High strength and high performance concrete.
- Structures with congested reinforcement.
- Improved cohesion allow for use in mass concrete pours and piling.
Hyperplast PC690 is available in 25 litre pails, 210 litre drums and 1000 litre bulks supply.
Hyperplast PC690 has a shelf life of 12 months from date of manufacture if stored at temperatures between 2oC and 50oC.
The recommended dosage of Hyperplast PC690 is 0.5 to 3.0% of cementitious materials in the mix, including
GGBFS, PFA or microsilica.
Representative trials should be conducted to determine the optimum dosage of Hyperplast PC690 to meet the
performance requirements by using the materials and conditions in actual use.
Hyperplast PC690 complies with ASTM C494, Type F.
