Product Description
ADVA® Flow 222 is a high performance, new generation mid-range water reducer based on comb polymer technology. This product is designed and suitable for application in high flow concrete or self-consolidating concrete. It is a ready-to-use liquid admixture with superior dispersing capacity for the cement particles in the concrete mix. This capability exceeds that of normal water-reducing admixtures, resulting in lower dosages and better control.
ADVA Flow 222 contains no added chloride. One litre weighs approximately 1.08kg ± 0.02kg. ADVA Flow 222 complies with the requirements of admixture specifications: SS 320: 1987; BS 5075: Part 3.
Applications
Excellent slump control and slump retention are necessary properties of any high quality concrete. ADVA Flow 222 is a tailormade admixture that helps concrete achieve excellent slump retention for all ranges of design workability. ADVA Flow 222 is extremely effective in enhancing workability and slump retention even in mid-slump concrete and concrete with manufactured sand (crush granite fines), where conventional admixtures have difficulties achieving these properties.
ADVA Flow 222 is suitable for a wide range of quality concrete, from low to higher grade concrete, by adjusting addition rate. The use of ADVA superplasticiser can help to provide further water reduction when very low water-cement ratio is needed.
Product Advantages
- Provides long slump life with controlled set times.
- Finishes easily without stickiness, tearing or spotty set characteristics.
- Less susceptible to segregation and bleeding.
- Highly efficient, producing desired slump concrete with no loss in strength.
- Quick and easy application to the concrete mix water for rapid batching.
Compatibility with Other Admixtures
Most water reducers or water-reducing retarders are compatible with ADVA Flow 222 as long as they are added separately to the concrete.
Caution should be exercised when using ADVA Flow 222 with a retarder, as excessive retardation can occur if the admixture dosages are too high. Pre-testing of the concrete should be performed to optimise dosages and addition times of these admixtures. The admixtures should not be in contact with each other before they enter the concrete.
ADVA Flow 222 is not compatible with DAREX® Super 20 and DARACEM® products.
