- Reduced thermal peaks
- High workability for longer periods
- Lower pumping pressure
- Resistance to segregation even at high workability
- Extended setting with longer workability
- Reduced water content for a given workability
- Higher ultimate strengths
- Reduced permeability
- Improved durability
- Reduced shrinkage and creep
- Increased ease in finishing concrete
- Provides lower in-place cost
Optimum dosage of MasterRheobuild 623 should be determined with trial mixes. As a guide, a dosage range of 400ml to 1200ml per 100kg of cementitious material is recommended as a starting point. In high performance concrete a dosage upto 1800ml per 100kg of cementitious material can be added subject to prior site trials.
