Advantages:
1. Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish.
2. High water reducing rate, 40% increase in 28 days strength. High strength after 8 hours.
3. Copatable with Portland cement, Normal portland cement, Pozzolanic cement etc.
4. Improve workability (slump) of concrete when added into mixing truck.
Dosage:
0.5-1.5% by weight of cement. Exact dosage rates are depending on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. It can be added during mixing and after-mixing (better), The after-mixing approach can achieve better result.
